5.1 xLogic Functions
PR series adapts programming methods by means of function blocks. A total of 9 general function blocks,
60 special function blocks, and 11 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 xLogic function blocks are available for options
：
5.2 General Input & Output functions
5.2.1 Inputs
Fashion: Classic:
Input blocks represent the input terminals of xLogic. Up to 4 digital inputs(ELC-6 CPU),8(PR-12
CPU) , 76 inputs(PR-18 ) 78 inputs(ELC-22) and 80 inputs(ELC-26) 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.
Note:
I11 means the I1 input of the expansion with address 1.
