※1: Firmware version below V3.4.5: the XD series PLC allows up to eight BLOCKs.
Firmware version V3.4.5 and above: XD/XL series PLC can write up to 100 BLOCKs, but at
the same time can only run 8.
※2: When the trigger condition of the BLOCK is triggered by the closure of the normally
open coil, it will be executed from the top of the BLOCK to the bottom in turn. When the last
instruction is executed, the execution of the BLOCK will be restarted immediately from the

immediately, but will complete the last scan and stop after the execution of the unexecuted
program.
※3:When the triggering condition of BLOCK is triggered by the rising edge of the coil, the
sequential function BLOCK will be executed one time from top to bottom and will not be
executed circularly.
