Freelance Modbus RTU communication
Hi, is there anyway to increase the scan time for Modbus RTU (RS-485) connection in Freelance? As currently one of my modbus RTU connected system is having this problems:
1. Transmitting is counting as per normal
2. Receiving takes very long time to count
(this causes the values displayed on digivis to take a long time to update)
Scene: We have 6 generators using this Modbus RTU connection in daisy chain, thus we noticed that the values we display for the 6 gen sets are very slow.
(e.g, Gen 1 is running since 1 day ago so we see the values and signals then they it switched off and change to Gen 4 but the Gen 4 data is not coming while Gen 1 data remains there for awhile. Only after like 5 mins or so, Gen 4 data comes in but if the current increases we cannot see the change immediately.)
At first we thought it was the baudrate setting as current baudrate is 9600.
Is there really any solution to increasing the scan time?
what is Parity error in the modbus status means? How to i trace what kind of parity error is it?
