77. How to Establish Communication Between i Series HMI and S7-1200 FW V4.0 devices?

Recently, Siemens has made great changes in S7-1200 Firmware V4.0; therefore, S7-1200 driver can no longer establish communication between EasyBuilder8000 and S7-1200 Firmware V4.0. To establish communication between i Series HMI and S7-1200 Firmware V4.0 devices, please use S7-1500 driver.

Please follow the steps to set up the environment for communication, otherwise, error may occur.
Step 1. Select [General] » [Protection] » [Permit access with PUT/GET communication from remote partner] option.
