- Set the communication port that communicates with MICRO/I to PPI/Slave mode.
Please make sure to set SMB30 or SMB130 values to 0 in order to select proper
communication port settings. Refer to the manual of S7-200 for details.
- We checked the following problems in some versions of S7-200.
When S7-200 is set as the master and the address of S7-200 is the same as HSA, token
path does not work correctly.
This problem can be solved by setting HSA as a larger value than Address actually used.
This problem does not occur when one MICRO/I is connected to one S7-200 PLC.
