I've a Siemens PLC S7 200 series connected to an industrial PC via multimaster PPI cable. The cable, a Siemens 6ES7 901-3CB30-0xA0) is configured with the dip-swith 5 ON (PPI mode used for remote programing thru modem). It works fine with the on-site modem & remote Microwin using a software, but it won't work with libnodave. The PLC works fine with libnodave if I set the switch 5 OFF (PPI/freemode), but it would be great if I can use libnodave communications with PPI cable switch set ON (PPI remote configuration for the cable) because in this way I could use libnodave on my SCADA (local) and eventually reprogram remotely the PLC via Microwin/Step 7.
There are any changes that libnodave works with the switch 5 of the PPI cable set ON? Libnodave connects to the S7 PLC but reading values in it goes in timeout if the switch 5 of the cable is set ON.
Thank you
Johnny
