Big problem with Modbus TCP
#1
Hi guys I'll hope you can help me!

I have an HL that communicate with 2 Risco intrusion stations and 2 Notifier fire stations and every station have 200 - 250 registers to read.
I use profiles, and my biggest problem is that: after few correct read, the HL, start to write wrong value on some group value and then stop to update all value of the register of the 2 fire stations, while the value of the 2 intrusion stations works correctly.

Between the HL and the fire station there's a moxa modbus converter that convert TCP modbus packets into serial modbus packets becauseĀ fire stations don't have only serial port.
From this converter I can see all packets that pass through, and I saw that HL every minutes send correctly questions and fire central answer correctly, but HL don't update group address..

Another think that don't work is the istruction "read_delay": 1 because the question that arrives to the moxa comes after 30ms and not 1 seconds that I write..

Someone can help me?
