Hi, the Modbus instructions should work on S7-300. So you can check if you have newest version of the FB - and you can check / post diagnostic buffer of plc for which reason the CPU has gone into stop. Check this link: PtP instructions for use of ET 200MP / ET 200SP in the distributed peripherals of a S7-300/400 with Step 7 V5.5Regards, Towome |
