I have a communication co processor module(CMM 311)installed in a GE 90-30 PLC.I have connected the PC serial port to the 25 pin port(tried with PORT 1 & 2) of the module using a custom cable.I am using versapro software.
1.Is it possible to establish connection between PC and PLC and to download ladder logic through a direct connection to this module?
if yes how?I couldn't establish a connection.The protocol setting and the serial port parameters seems to be matching.
2.Is there any free third party software by which I can read the register contents of PLC in a PC connected directly to the CMM 311 ?
3.When I tried to store hardware configuration and logic to the PLC flash,I 'm getting a message 'Insufficient privilege level'.The CPU passwords are disabled and the privilege level 4 is chosen.How can I get around of this problem??
thankyou
