Re: s7plc more than one 240-byte PDU

OK, thanks I'll see what the PLC guys says about that.  That was my first thought, but then I didn't see how on the PLC side to direct the send-block mechanism to an ipaddr:port .

Hello Paul,

If you cannot increase the block size (the driver has no limit on this but maybe the PLC) you can have two blocks on the PLC running on different ports. To the IOC this would look like two devices.

I have been using s7plc driver for years with one SND and one RCV block on the PLC.  Now, we need to send more data than can fit in the (max size) 240-byte block.  How can I send more data to EPICS?
