In Documentation we talked about refresh time, response time for the BMX AHI module .
Difficulty is to undesrtand what is the meanning and difference about those two terms .
Response time only makes sense when talking about a specific channel.
Response time is the delay time between external stimulation and the PLC read value, it only makes sense when talking about a channel. Because the different channels get the different external stimulations.
If all the eight channels for AHI change from 4mA to 20mA at the same time (change finished within 0ms), then the read values for all the eight channels will arrive 10000 after 50ms (assume 4-20mA = 0-10000).
