Here is the scenario, recently my laptop had virus/worm issues so I have reformatted and just today got all the programs reinstalled and all associated authorizations. I have an IBM 390 300 mhz with 64 meg ram and running Windows 98SE.
Tonight I got called in for a problem with a machine that has an S7-314IFM as Master, 312 as slave and an OP7. All the voltages, connections, devices seemed to be operating correctly. I could get inputs from various switches but no action. To give background the Slave processor is not needed for standard running, its there for a secondary function..ie nothing I have found indicates the Master needs the slave to run altho I have never disconnected one to verify. Likewise the OP7 is needed to set parameters in the Master but there is no indication that it HAS to be connected once any parameters are entered.
Anyway this is not the first time one of these plc's have not functioned properly so I concluded it was the program or plc that had a problem. I connected to a spare plc and attempted to download the program (I have 12 of these machines that are identical and all 12 programs on disks), it seemed to download but as usual since all 3 items werent connected I got an address error message once download was complete (this has happened before when programming one of the devices alone).
Now comes the strange part, I attempted to connect to the problem PLC to reinstall the program and SIMATIC just froze. After several attempts I swapped plc's and tried the new one, it wasnt right so I attempted to connect to it and SIMATIC froze. Naturally I made several attempts.
I have found nothing so far that shows a problem external to the plc..ie an input etc but will check more tomorrow.
My question is has anyone using a CP5511 pcmcia card and Simatic S7 ever had a problem connecting to download/upload or even Display Accessible Nodes? I have checked the Siemens database on issues with Win98, CP5511. It seems there are some issues with an Ethernet card especially a 3COM which I do have and it was in but not being used. Tomorrow I will try again without the 3COM card in.
ANYWAY, have any of you had to suffer thru any issues similar this? I know its hard to state much without being familiar with the machine but any info you have pertaining to this may be helpful.
Thanks in advance.
