Hello there,
We have an application where we would like to place a high speed counter card in a remote I/O rack. My concern is communication speed in relaying the counter values from the counter card back to the plc.
The field devices are flow meters. I don't know exactly what the pulse train frequency is. Maybe around 5 khz. Can someone explain the steps involved in retreiving the counter values from the counter card and resetting the counter register once the plc has retreived the current value. What is the most accurate way of recording flow totals to a register in the PLC?
Thank you in advance.
