10.2.8 Set Modbus™ Timeouts
The Set Modbus™ Timeouts menu establishes the response timeout for Modbus™ communications and the
inter-poll delay. Response timeout is the amount of time in milliseconds the CXT controller will wait for a
sensor to respond to a poll request. Inter-poll delay is the amount of time in milliseconds the CXT will wait
after receiving a poll response from one sensor before it polls the next sensor. Ten missed poll responses
will result in the sensor being declared in COMM ERR. The range of values for the response timeout is
100-1000 milliseconds and 10-255 milliseconds for the inter-poll delay. The recommended value for the
response timeout is 500 and 150 for the inter-poll delay.
