FUNCTION CODE DEFINITIONSENHANCED ANALOG SLAVE DEFINITION FUNCTION CODE (FC 215)I-E96-301B C - 3S1 Specification S1 is the analog slave expander bus address ofthe Universal Analog Input Slave Module (IMASI03).S2 This specification contains the block address of the firstEnhanced Analog Input Definition (Function Code 216) func-tion block describing one of the channels on the slave module.S3 This specification contains the block address of the cold junc-tion reference temperature used for compensation of thermo-couple inputs. S3 should refer to the function code 215 outputblock if the built-in cold junction reference is used (see FigureC-1). The value of the function code 215 output block is indegrees C.If a remote cold junction reference is needed, refer to functioncode 216 specification 4 and Note 3 in Table C-7. Figure C-2shows an example of remote cold junction reference.Select the cold junction reference input by configuring specifi-cation 3 of function code 215 with the block output of the coldjunction reference for the slave addressed in specification 1 offunction code 215.Figure C-1.
