My project consist of CPU S200-224xp and two LENZE inverters (8200 vector) The network use LECOM-B protocol PLC is master and inverters are slaves I use Freeport protocol on port0 I use for write on port0 XMT instruction I use for read from port0 RCV instruction I use three interrupts XMT complete (event 9) RCV character (event 8) RCV message complete (event 23) In my program the first interrupt {XMT complete (event 9)} is always active But the others inactive before sending and on XMT complete interrupt one of them become active to read the receiving data (ack/nck or parameter value) My problem happened when the connection in the network breakdown (cut) for any reason Then a Run-Time error happened and I get this message "Simultaneous execution of XMT/RCV instructions on Port 0" I attach my program file From PLC information the error happened on (LENZE_SCAN) subroutine at network 5 Thanks Attachmentprogram.zip (672 Downloads) |
