zht Posts: 4 Rating: (0)	Hi, I have a communicationproblem betweeon two PLC. I send datas from PLC1 to PLC 2 when PLC2 need new datas with using SFC65-66. But sometimes some datas are missing. For example; I want to send datas from PLC1 to PLC2 respectively A34-A35-A36-A37. But I dont know the reason sometimes it skips one data. So it can be look like; A34-A36-A37. And I want to prevent this.And how can I be sure correct data go to PLC2? Regards
