3After executing the command, the HS500E writes the response in the Write Tag and then increments the counter in EMS_WRITE1 [1]. This signals that there is new information for the PLC (the HS500E generated response).

4After the PLC has processed the response information, it copies the counter from EMS_WRITE1 [1] to EMS_READ1 [0] which signals (to the HS500E) that the PLC has read the response data.

5The HS500E will then clear the Write Tag by copying 0’s to memory. After which it will be ready to receive another command.
