Communications configuring Channel on the data interface In the configuring example, both message evaluation blocks set-up a channel at the data interface D01 in the "select" mode (thus, the same channel name can be configured). Measured value input and message signals The measured value input of block MER is not connected in the particular example. At the measured value input, a process condition is normally applied. The message signals of function block MERF0 act similarly. Generating and reading-out messages Messages are generated by a rising edge at connection I1 of block MER or by a changing value at input IS1 of block MERF0. The message evaluation block immediately reads-out the first message from the message buffer and transfers into the data channel as both blocks are "enabled" (input EN=1). Additional messages are only transferred into the data channel when the previous message has been read-out of the channel. 3-242 System- and communication configuring D7-SYS - SIMADYN D Edition 12.2003
