IMPORTANT i20 refers to an Acromag proprietary method of input to output communication done over the network without other hard wired connections between inputs and outputs This is not a Modbus TCP IP function and the i20 mapping feature of this model may only be configured via this software As such there are no Modbus registers for specifying i20 parameters Under normal operation this module is designed to function as a Modbus TCP IP slave server By the Modbus standard Modbus servers are not allowed to initiate messages on their own and may only respond to client master requests Thus the i20 functionality of this unit is a special application that may cause confusion for some other master client devices linked to the same network In any case other master devices on a network should be restricted from attempting to control i20 target devices on the same network to avoid contention Note that you must disable the Coil registers option at the target module in order for i20 to successfully write to the target output this requirement only applies to XT1531 000 and XT1541 000 targets Acromag Inc Tel 248 295 0880 27 http www acromag com BusWorks Model XT1541 000 8 CH Voltage Output 4 CH Digital I O w USB amp Modbus 120 Mapping With i2o a client server network connection is established between a sending module client and a target output module server This connection refers to an established data path or socket between
