How to configure communication between ALR121 and S7-200, and what aspects need attention?
Reply #22016-11-30
The key is still to get the communication settings for the S7-200 right; once that is done, it becomes much simpler with the Yokogawa ALR121. To make the S7-200 act as a Modbus RTU slave, PORT 0 must be used. Additionally, the Toolbox, which is the Modbus communication instruction library, needs to be installed on Micro/Win.

Where should the TOOLBOX be installed, on the host computer? Are you referring to the MODBUS protocol used in S7-200?
