Response timeout in ms If a response to a sent frame is not received with this time, then the frame is transferred again. After the third retry, the connection is deemed canceled. The time in which an interrupted connection is detected is a result of ResponseTimeout * 4. Setting /RT=0 uses the INA2000 default value (275 ms). Example: "/RT=400".
Recommended values (at a baud rate of 115200 bits/second): 100 - 200 ... For connections with only variable communication to SG4 controllers with sufficient idle time with AR 3.00 or higher. 200 - 500 ... For connections with only variable communication to any target systems / AR versions. 500 - 1000 ... For connections with PLC services running (e.g. Automation Studio project transfer). |
Additional parameters for the INA2000 CPU can be found under "General parameters". |
