6.1 x-Messenger Functions
EXM series customized mode adopts the programming methods by the use of function
blocks. A total of 8 general function blocks, 30 special function blocks, and 6 input &
output function blocks are configured. And each block can achieve a specific control
function independently, e.g. TOND, TOFD, SBPL, TBPL, SCHD, etc. As several blocks are
linked up in a specific way, relatively complicated control functions can be performed.
Programming with function blocks is simpler and better appreciated than the
conventional PLC instruction programming.
The following types of operator for x-Messenger function blocks are available for options
：
6.2 General Input & Output functions
6.2.1 Inputs
Input blocks represent the input terminals of x-Messenger. Up to 8 digital inputs are available to
you.
In your block configuration, you can assign an input block a new input terminal, if this terminal is
not already used in the circuit program.
