Help with RS-232 ASCII Communication - SoMachine

[Kiwi_Karl]

Hi, 

I'm currently trying to set-up a M241 PLC to communicate with a Rigol Multimeter via RS-232 using the ASCII manager. 

I have had success sending commands to the multimeter (and hyperterminal on a PC) from the PLC using the example below from the 

SoMachine Modbus and ASCII Read/Write Functions PLCCommunication Library Guide 

I have taken this example and modified it in order to try and receive a basic message, initially from hyperterminal, See 'Current receive example' below, however I am yet to get this working. 

Can anyone share an example of code used to receive a message using this SEND_RECV_MSG function block? Or provide a hint as to where I am going wrong? 

Send Example:

 

Current Receive Example:

 

The PLC is connected to my computer using a RJ45 to serial cable and a serial to usb converter.

I believe I have the ascii manager and cable set-up correctly as I am able to send messages from the PLC to hyperterminal.

Thanks in advance, 

Kiwi_Karl
