Remote Operations Devices Ideas

We know Accutech product line, is a family of instruments reporting to a Base Radio and user ( PLC or SCADA ) can read each instrument information using 10 double word registers.  We can read temperature , pressure and also voltage or current to join into the accutech network any standard 4-20mA or 0-10V devices.  BUT imagine if we can integrate into the Accutech Network a Modbus slave ( or modbus TCP/P ) device.   Just only read or write 10 registers. We can incorporate in a wireless network many devices like Variable speed drives, other brands instrumentation , PLCs , Energy measurement.....   The hardware to implement  this idea exist already , is the BR20 or BR21,  the only job to do is modify the firmware to use the serial ports to read 10 registers from the modbus device and transmit that to the Accutech Base Radio as other Accutech instrument.  We will can convert to wireless any modbus device in the field or plant.  This idea has a grate potential in the market, also against competitors, they are unable to do that.    What do you think?  ...

I would like to suggest a change to the Controller Key feature found in Telepace Studio 5.4.2.  I originally submitted this as a bug but because the Controller Key feature prevents writes to the PLC ladder program it was referred to this forum.  In summary, changes can be saved to the project when the Telepace editor is exited, which could (under certain circumstances) lead to corruption.   It is true that the ladder program will not be sent to the PLC if the “WRITE” button is not pressed but I suggest two failure scenarios here.  Maybe a bit unlikely but I present them for review nonetheless:   First, unexpected changes could be saved to the project by a bad person; if the project is ever opened by an authorised user who actually needs to modify the project, and if all sheets are not checked thoroughly before writing/saving, the legit user could inadvertently commit the hacked changes along with the intended modifications.   Second, the “Controller Lock” tends to imply that the project is secure, at least in my mind.  I would prefer that project changes were “bundled” into the controller lock as well as the WRITE commits.   I respectfully suggest that edits to the project are discarded if the Controller Lock is enabled and the "Save changes?" dialog not displayed so that the hacker is not sure what is happening.  This would indicate that the Controller Lock feature not only controls the written PLC ladder program but the project as well, which is the same thing just in un-committed form.   I am recommending these two changes to the next possible release of the Telepace editor.  The changes would make the editing environment more secure than it already is.  Thank you for providing this forum to submit these types of ideas. ...

I recognize ongoing support of IsaGraf based ScadaPack 300-series Modbus RTUs is lower priority than new products/features, but the inability to embed source code onto RTUs for upload later in Workbench 6 is a real bummer, and a deal breaker for many of my end users who I'm still supporting in IsaGraf workbench 3.55 and WinXP 32-bit VMWare images.   Please consider restoring the ability to embed/upload source code on the older hardware. ...
