I have an M251 connected to an EGX, which interfaces with four slave devices. The data is sent to the PLC through the EGX. I've noticed that the data monitoring process is quite slow, leading to data loss, especially when energizing an incomer associated with one of the slave devices. Sometimes, I experience significant delays in data updates or the data might not be updated at all, and I have observed this warning in Machine Expert. Could this warning be related to the issues I'm facing? How can I address the data delay or loss problem overall?
I have to mention that when I use any MODBUS scanner to read the data directly from the EGX sometimes I get a timeout error
