Issue How many messages are buffered on a Door Controller 7910A and 7920 DPU? Product Line TAC INET Environment I/NET Seven Door Controllers: DPU 7910A, DPU 7920, and SCU 1284 Cause Even though every device in the system contains a message queue, only a few of the devices will successfully buffer the queued messages for later distribution. All controllers and Taps distribute messages out of their RS485 port even with the absence of any LAN communication. This is due to the fact that there is no requirement for an acknowledgment to be received at the generating device. The RS485 LAN is for both solicited and unsolicited message traffic. The only devices that perform extended buffering are the ones that directly communicate to polling devices such as the 7801 Taps, 7803 Taps, 7804 Taps, and all DPUs/SCUs. The MRs, ASCs, and UCs do not generate messages; messages relating to these devices are generated by the relevant MRI, MCI, etc. Resolution Refer to the Database Caching in the Door Controller Chapter 9-11 in TCON 300-05/17 for full details. For the 7910A and 7920 see the following details:  Controller software before v.2.20 = 100 messages Controller software for 2.20 and later = based on the number of resident individuals (see table below).

Issue A more in-depth description of each of the Direct Digital Control (DDC) modules in I/NET Product Line TAC INET Environment I/NET DDC DCUs, PCUs, MRs Two Position Module (2POS) PID Controller (PID) Float Module (FLT) Reset Module DDC Hi/Lo Module (HI/LO) Relay Module (Single Pole Double Throw Relay) Calc Module Cause DDC is a system that measures a variable, compares the variable with a known value to determine the error, processes the error using a specific software algorithm, and then produces an output to modify the controlled variable. Resolution Most of these modules are discussed in both TCON 083 or  TCON 299 System Operator Guide for more details. (The System Operator Guide is installed by default on your I/NET Host Workstation) DDC Two Position Module (2POS) This module is used where the final control element is in either one state or another opposite state (ON/OFF, OPEN/SHUT). This type of control will commonly be used for simple heating or cooling systems, starting and stopping motors, controlling water sprays for humidification, etc. This module is available in our PCUs and DCUs; and you can customize it for your needs.  DDC PID Controller (PID) In Proportional (P), Proportional + Integral (PI), and Proportional + Integral + Derivative (PID) control, the control element moves linearly to a position that is proportional to the deviation and the rate of deviation of the controlled process variable from a prescribed setpoint. This type of control, in any of its three modes, or combinations thereof, is commonly used for the control of modulating valves, vanes or modulating motors where a proportional output control point is used. The proportional output control point may be either an analog output (voltage, current, resistance) or a pulse width output where the duration of the pulse is proportional to the error variation. This module is available in our PCUs and DCUs; and you can customize it for your needs.  DDC Float Module (FLT) Traditionally, floating control actuates a control device when the error, i.e. the difference between the controlled process variable and the setpoint, exceeds a deadband and maintains the control until the error is within the deadband. The floating controller is based on the same principle however it has been enhanced to include PID control without the requirement for analog output or pulse width position feedback. The output of this controller may be directed toward either a pair of variable pulse width discrete outputs to control a bi-directional drive motor or dual EP value arrangement which is generally described as a "pressure-vent" controller. This type of control is commonly used for the same applications as the PID controller where positive feedback is either unnecessary or economically unsound. This module is available in our PCUs and DCUs; and you can customize it for your needs.  DDC Reset Module (RESET) Reset is used to develop a setpoint output in an inversely or directly proportional relationship to one or two analog inputs and one or two operator-specific reset schedules. This module is available in our PCUs and DCUs; and you can customize it for your needs.  DDC Hi/Lo Module (HI/LO) This module is used to provide the highest and/or lowest value from two or more measured variables, most commonly temperatures. HI/LO can be cascaded to accommodate virtually any number of inputs of similar nature. Typically the lowest space temperature would be the most logical to use to directly reset the heating water setpoint. The HI/LO modules provide the control engineer with a convenient alternative method for making the selection. The HI/LO modules may also be used as an OR/NOR selector by using the state(s) of various monitored discrete points. This module is available in our PCUs and DCUs; and you can customize it for your needs.  DDC Relay Module (Single Pole Double Throw Relay) This module provides a mechanism for selecting one of two values or states based on conditions within the controlled environment. The actions of the relay are controlled by one discrete input and control which of two input states or values is directed to the output. The inputs and output may be either discrete or analog. The actions of this relay are analogous to its electric/electronic counterpart in its simplest form. This module is available in our PCUs and DCUs; and you can customize it for your needs.  DDC Calc Module This module functions similarly to calculations added to a point through the calculation extension editor. This module is only available in Micro Regulators (MR). It is not available in Application Specific Controllers (ASC). 

Issue An SP-RDM2 will be used to add doors to an I/NET-transitioned site. The readers connected to the SP-RDM2 will need to read Hex Card Number credentials. Product Line Security Expert, TAC INET Environment Security Expert Controller (SP-C) Security Expert Reader Module (SP-RDM2). Cause After transitioning an INET site to Security Expert, you may find it necessary to add one or more new doors. In Security Expert, you add doors to your system by attaching one or more SP-RDM2 modules to the RS-485 bus of an SP-C (up to two doors per SP-RDM2). That is still true for the transitioned system; however, some configuration tasks must be performed to allow the SP-RDM2 to coexist with the SCUs and DCUs that are already communicating with the SP-C.  You will also configure the SP-RDM2 to use the custom Hex Card Number credential you created as part of the INET transition process. Resolution For an SP-RDM2 module to work in conjunction with I/NET modules it must be configured in a specific way. You will need: SP-C firmware 2.08 build 911 or later SP-RDM2 firmware 1.12 build 546 or later Configuring the SP-RDM2: To the existing transitioned I/NET site, add a new Reader Expander for the additional SP-RDM2 reader module. (Note that the last reader expander defined in your existing system may be assigned to a dual-address SCU. If this is the case, make sure the address you assign to the SP-RDM2 is at least two addresses higher than the SCU to avoid address conflict.)  Set the Reader 1 Format and the Reader 2 Format to "Custom Credential". (Note that if the Port 1 Network Type or Port 2 Network Type is set to "Schneider Electric RS485" then this will need to be changed to "Wiegand" to allow you to set the reader format; it is greyed out otherwise. The network type can be set back to "Schneider Electric RS485" afterward.) Set the Port 1 Network Type and Port 2 Network Type according to the type of readers that are connected. In order to correctly convert the card read to the hexadecimal credential format that is programmed for the users, the reader expander must know what card format is being presented. This is done using commands. For the reader on port 1, add the command "R1RawFmt = #" where # is one of the descriptions shown in the table below. Similarly for the reader on port 2, add the command "R2RawFmt = #" where # is one of the descriptions shown in the table below.  If the command is absent, then Wiegand 26 is used as a default. Command Card Type R1RawFmt = Wiegand 26 26-bit Wiegand R1RawFmt = Wiegand 32 32-bit Wiegand R1RawFmt = Wiegand 34 34-bit Wiegand R1RawFmt = Wiegand 66 66-bit Wiegand R1RawFmt = Custom Wiegand Any Wiegand card - parity check is skipped Additionally, the SP-C controller must know which reader expanders to expect on the I/NET network and which reader expanders to expect on the Security Expert module comms network. By default, if the controller command "INET = true" is present in the SP-C, then all modules are considered to be on the I/NET network. Adding an SP-RDM2 to the Security Expert module comms network with no additional commands will result in partial operation but there will be problems. To use a mixture of I/NET modules and Security Expert modules, a command must be added to the programming of all I/NET modules. This command is: "HardwareType = INET" If this command has never been added to any module, and the command "INET = true" is present in the SP-C, then all modules are treated as I/NET. This maintains backward compatibility with existing sites. As soon as the "HardwareType = INET" command has been added to even one module, then it must be added to the programming of all I/NET modules from then on for the site to function as expected. Configuring the SP-RDM Doors to Accept Hex Card Number Credentials Create a new Door Type for reading cards as a Hex Card Number credential and configure it as follows. In the Entry section on the General tab, set the Entry Reading Mode to "Custom". In the Entry Credential Types section, add the "Hex Card Number" credential type. Save the Door Type. Configure each door on the SP-RDM2 to use the new Door Type as follows: In the Setup section on the General tab of the door, set the Door Type to the name of the Door Type you just created in step 1. Save the door.

Issue PID module has gone to "control-point" Product Line TAC INET Environment I/NET DDC PID Cause The PID may have gone to "Control Point" due to unforeseen circumstances and is causing a problem. "Control Point" can also be used intentionally as a control strategy. Resolution Four reasons: If the Setpoint’s value crosses above or below the high or low input limits as populated in the PID editor, this will force the PID to go to control-point. If the process variable should reach the low or input sense limits as entered in the Resident I/O editor, the PID will go to control-point. If either the Setpoint or Process variable should go to "OLD" status, the PID will go to control-point until the "OLD" flag goes away. If the user should change any variable within the PID, when exiting the PID editor, the PID will go to control-point until the next scan of the module. For more information on this subject refer to Tech Tip G062.

Issue Set up a MR-VAV-AX (ASC) as Standalone Product Line TAC INET Environment MR-VAV-AX Cause Air balance must be done to calibrate the airflow sensor on the MR-VAV-AX. Resolution Download Tech Tip 072   Equipment: Air Balancing Hood or Manometer and Digital Thermometer.   Assumptions: The MR is powered up. An I/STAT, or an M/STAT is plugged into the service port of a S/STAT or W/STAT, which is plugged into the MR-VAV-AX. The AHU is running. The Space sensor is installed. The Duct static pressure is constant. The dip switches are set properly for the desired VAV configuration. (See TCON 147) You have a Pocket Reference Card (TCON 149). You are familiar with the use and operation of the I/STAT / M/STAT with respect to navigating the Service mode to various mnemonics’ menus. (See TCON 147)   Initial Setup You should notice that two things have already happened: The MR is in the unoccupied mode. The setpoint adjust has defaulted to "-5", making the setpoint display appear low. For the MR to work in a Standalone mode the use of an off-board time clock for the occupied and unoccupied times is recommended. It should be connected to the "Local Occ" point(TB5 input #2 to TB5 ground.) The "Occ" mnemonic under Unit Parameters must be set to ONE for the "Local Occ" point to be used. If the MRs are to be left in the occupied mode indefinitely, install a jumper across the "Local Occ" point instead of using the time clock contacts. Connect the jumper to (TB5 input #2 to TB5 ground.) Using the I/STAT or M/STAT go to Set Temp and increase the value by 5°. This will get the Setpoint Adj. back to zero.   "Cooling Low Flow" (CLF - min. CFM) and "Cooling High Flow" (CHF - max. CFM) Setup Put the I/STAT or M/STAT into the Service Mode. Go to "AP", select "CLF", (the value displayed is "multiplied by" 1000 so 0.24 is 240). Enter the minimum CFM by using the arrow keys to position the LED for the digit to be changed and enter the value by using the "+" and "-" keys. Notice the decimal position will not move. You are entering the value "multiplied by" 1000. Refer to the Pocket Reference Card (TCON 149), paragraph 5. Usually the minimum air flow value can be found on the Mechanical box schedule drawings. The lowest reading that the ASC’s sensor can sense is about .03" to .05" of Water Column(W.C.) Therefore, the "CLF" must be set above this level. If the ASC is required to control in that range, it will tend to oscillate. Select "CHF" and enter the maximum CFM for this box at 1" W.C., this can be found on the DeltaP to CFM graph that is associated with this VAV box’s pickup device, or the box schedule may also provide the maximum cfm value.   Central Plant Heat "Heating Low Flow" (HLF) and "Heating High Flow" (HHF) Setup Use only if Central Plant Heat is required and setup Unit Parameter’s(UP) CPH set to "1". An open contact at Input 3 will indicate that the Central Plant Heat mode is on. A closed contact indicates CPH is off. Using the procedure described above for "CLF" and "CHF" instead select "HLF" and "HHF" and enter the desired Low and High Flow CFM values for the Heating Mode. Otherwise go to the next section. NOTE: If you have a auxiliary stage of heat, it will not be energized unless the CFM input is reading at least 80% of the "HLF" setting.   Calibrate the flow pickup: Go to Unit Parameter "UP", select "dd" (duct diameter). Enter the duct diameter this will enable the MR to calculate the Pickup Factor "PF" for us. NOTE: It is recommended that you begin with the value provided by the VAV Manufacturer for the pickup factor. Then calibrate if necessary using the following procedure. Go to "AP", select "PPF" (pickup factor calibration). The MR will drive the box open and modulate the damper to maintain the "CHF" level. This may take 5 - 10 minutes. NOTE: The stroke time is defined using the Damper Stroke (ds) parameter. The ASC provides several means of synchronizing the point with the physical damper position. 1. When this point is controlled to a value of 0, the decrease pulse will be on for 125% of the damper stroke. 2. When this point is controlled to a value of 100, the increase pulse will be on for 125% of the damper stroke. 3. When the damper stroke duration is modified, the decrease pulse will be on for 125% of the damper stroke. 4. When the power is cycled on the ASC, the decrease pulse will be on for 125% of the damper stroke. 5. Any time the ASC is the target of an Update_ASC or a Copy_Parms, the decrease pulse will be on for 125% of the damper stroke. After the reading has settled out, take a reading with a Hood or Manometer, which has been setup, and measure the actual CFM and enter that value now into the I/STAT-M/STAT using the Select and change buttons. The software has entered a unique Pick-up Factor "PF" in the MR for this box.   Calibrate space temperature (if necessary): To calibrate the Space Sensor while in the Service Mode, go to "oP" Operational Parameters. Select "CSS" (calibrate space sensor). Measure the actual temperature with a digital thermometer and enter the value. If your box has no heat or has a fan with electric heat. You’re finished. Go to the next box.   Hot water coil: If you have a hot water valve on your box and the stroke time is not 600 seconds: Go to "UP" (Unit Parameters) and select "Ho", Heating Output. Select1 for 1-OutPWM, 2 for 2 Out-PWM(Floating), or 3 for Duty Cycle 1 output. Go to "UP" Unit Parameters and select "HS" (heating stroke) and enter the actual stroke time in seconds.   Air Balance: If you require closely calibrated CFM readings proceed with the following steps: Go to "AP" (Airflow Parameters) Select "CPL" (calibrate low flow) and the damper will begin to close. Remember, the damper motor may take 3 minutes to get to the Cooling Low Flow setpoint. With a Hood, measure the total air flow and enter the measured CFM value. Select "CPH" (calibrate high flow). The damper will drive open to the Cooling High Flow setpoint. (remember the damper motor has a 185 sec stroke). When the reading stabilizes, take your measured CFM reading and enter it now. This procedure will de-calibrate the CFM input from the 0-1"readings to compensate for box, pickup, or hood irregularities/errors. Caution: When the decision is made to connect the MR-VAV-AX to a MRI or MCI please note the following: Avoid updating the MCI or ASC after initial setup as this will delete any MCI resident calculations, ATS, etc. that you may have added off-line that are residing at the same point addresses that the MR-VAV-AX is using. There are a variety of box types and a variety of other things that can be change if your application requires it. (Refer to TCON147)

Issue Can DDC lines in ASCs be displayed on I/NET Graphic Pages? Product Line TAC INET Environment I/NET .gpg graphics DDC Lines Cause DDC Lines are represented different from Resident I/O points. Resolution Yes. The following Lines are the most common to view: Line 1 = Active Cooling setpoint Line 4 = Active Heating setpoint Line 5 = Active setpoint (*see below) Line 10 = Cool CFM setpoint (only on VAV-X2) Line 12 = Airflow setpoint (only on VAV-AX and X1) Line 14 = Mix Air (only on AHU w/ mixed air econ. control) Line 15 = Warm CFM setpoint (only on VAV-X2) Line 26 = Cool Air Flow (only on VAV-X2) Line 27 = Hot Air Flow (only on VAV-X2) * Line 5 should be the same as the value displayed on the STR-250, I/STAT, M/STAT. It will display either line 1 or line 4's value, whichever one is closer to the current space temperature. If average is selected for SPD, then line 5 will show that averaged value even though the controller is operating on the actual heating or cooling setpoint. For a complete listing of all ASC points and lines, see ASCLines.pdf.
