to all

• Operation of all function blocks by turning power ON to the PLC (Hot or cold start can be specified.) For
cold starts, function block data is transferred from flash memory to RAM.
• Function block operation can be stopped by CX-Process Tool or FINS command.
• Hot start (state active before Board was stopped is continued before operation is started) or cold start
(all state signals and function block internally held values are cleared before operation is started) is
possible by CX-Process Tool or FINS command.

Function block operation can be stopped and hot start (state active before Unit was stopped is continued

Function block
operation cycle
Standard: Operation of all function blocks is executed at the same operation cycle preset to ITEM 004 in
the System Common block.
Settable operation cycles: 0.1 s, 0.2 s, 0.5 s, 1 s, 2 s (default: 1 s)
Note: Cannot be set to the same operation cycle for some function blocks.
Option: Operation of individual function blocks is executed at the same operation cycle preset to ITEM 004
in the System Common block.
Settable operation cycles: 0.01 seconds, 0.02 seconds, 0.05 seconds, 0.1 seconds, 0.2 seconds,
0.5 seconds, 1 second, and 2 seconds (default: 1 second)
Note: The external I/O response cycle on a single control loop does not necessarily match the operation
cycle. The response cycle is heavily dependent on the CPU Unit's cycle time. (See the external I/O
response cycle item below.)
Function blocks

The following operation cycles can be set for the blocks listed below: 0.01, 0.02, and 0.05 s.

Execution
of
LCB load rate
function
blocks
The "LCB load rate" refers to the ratio between the actually applied execution time and preset operation
cycle.
The maximum value and current value are displayed for each operation cycle group on the CX-Process
Tool.
A LCB load rate of 80% or less is required in all operation cycle groups.
When the load rate exceeds 80% for 6 seconds, the LCB load rate automatically changes to the next
longer operation cycle. (This is called the "automatic operation cycle switching function.")
Note: The High Load Alarm Flag (A42408) turns ON if the load rate exceeds 80% for 6 seconds
consecutively (non-fatal Inner Board error). (If execution is not possible within the operation cycle,
the operation cycle will be extended.) If this happens, select the function blocks that can have longer
operation cycles and increase their operation cycles. If the load rate is still too high, processing of
the function blocks must be separated for processing by additional Loop Control Units.
External I/O response cycle
The time from external input of analog signals up to external output of analog signals on a single control
loop depends on the function block's operation cycle and the CPU Unit's cycle time.
