Hello gzzv; Hati still has a good memory. ;-) This IM 151-8 is a CPU of the ET 200S family, which is considered part of the S7-300 family. "The IM 151-8 PN/DP CPU is based on the S7-300 CPU 314." (extracted from this link): https://support.industry.siemens.com/cs/ww/en/view/30851575 You do not require a seperate communication module forModbus TCP with this CPU, it has an integrated Profinet port. You can use the integrated Profinet port of this CPU for Modbus TCP communications (without affecting concurrent Profinet comms) by adding the licene described in these documents: - How do you establish a Modbus/TCP communication from a SIMATIC S7-300/S7-400 and where can you find further information? https://support.industry.siemens.com/cs/do/en/view/22660304 Modbus/TCP PN CPU Integrated PROFINET interface of the CPU: license 6AV6676-6MB20-3AX0 - configuration of Et200S im151-8 pn/dp on modbus communication Hope this helps, Daniel Chartier |
