Yokogawa AAI143-S53 Analog Input Module (Current Input) Prox/Velom I/O Module # 1 RS422 channel interfacingThe analog I O modules (with HART communication function) communicate with field devices and store analog data and HART variables in the Input Output image area in the communication module. An FCS refers to and sets the Input Output image by accessing the analog I O modules (with HART communication function). The FCS utilizes the field device data via I O terminals of the function block in the same way as other analog digital I O signals. Technical
