Communication services
The IM 467/IM 467 FO offers two communication services:
● PROFIBUS DP
The IM 467/IM 467 FO is a PROFIBUS DP master in accordance with EN 50 170. It is
configured entirely with STEP 7. It behaves in basically the same way as the integrated
PROFIBUS DP interfaces on the CPU modules (see the specifications of the IM 467/IM
467 FO for the differences).
DP communication does not require any function calls in the STEP 7 user program.
● S7 functions
The S7 functions guarantee optimal and easy communication in a SIMATIC S7/M7/C7
automation solution. The following S7 functions are enabled for the IM 467/IM 467 FO:
– Programming device functions via PROFIBUS DP
– Operator control and monitoring functions via PROFIBUS DP
Communication takes place without any additional configuration on the IM 467/IM 467 FO.
S7 functions can be used on their own or in parallel with the PROFIBUS DP protocol. If
they are used in parallel with DP communication, this affects the PROFIBUS DP bus cycle
time.
