We recently got another piece of equipment in from one of our plants that is closing and yet again it is something we dont already have. The machine contains a Siemens 27-200 PLC/CPU212
In a box that came with the machine the folowing came along:
Software: STEP7-Micro/WIN 16, Vers. 2.11
Communications Cable: Siemens PC/PPI Cable
The cable has 6 dip switches on it.
Switches 1-3 configure the baud rate which was set for 9.6K
Switch 4 is 10 or 11 bit. It was set for 11 bit
Switch 5 is DTE or DCE and is set for DCE
I have no what the program that is in the PLC looks like or how it is set up. Does anyone have any advice on the best DIP switch settings on the PC/PPI cable for me to be able to communicate with the PLC.
I left all the communications cable switch setting the way they were when the machine came in and went into the software and clicked on Setup and then on Communications:
The communications window showed the following
PC/PPI Cable
Local Station Address: 0
Transmission Rate: 9.6kbps
Com Port: 1
Remote Station Address; 2
when I click on TEST SETUP it shows communicaton failure.
Any suggestions anyone might have will be greatly appreciated. All i want to do is be able to connect to the PLC and copy the program that is loaded in it just in case there are problems in the future.
Thanks
