Function block data preparation/ download			Function block data prepared by CX-Process Tool (sold separately) and downloaded to Loop Controller
Execution of function blocks	Function block execution conditions	Common to all function blocks	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.
		For individual function block	Function block operation can be stopped and hot start (state active before Unit was stopped is continued before operation is started) is possible by CX-Process Tool or FINS command.
	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 supporting high-speed operation		The following operation cycles can be set for the blocks listed below: 0.01, 0.02, and 0.05 s. Control/Operation blocks: Block Models 016, 150, 151, 155 to 157, 167, 182 to 184, 186, and 221 to 224 Sequence control and Field Terminal blocks
Execution of function blocks	LCB load rate		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.
Internal Operation	Number of control loops		The maximum number of loops that can be used if the LCB load rate is 80% for a standard applications (e.g., with each loop consisting of one Ai4 Terminal, Segment Linearizer, Basic PID, and A04 terminal) is shown in the following table. CJ1G-CPU43P/44P/45P (LCB03)

			0.01 s: 20 loops	0.02 s: 35 loops	0.05 s: 70 loops
			0.1 s: 100 loops	0.2 s: 150 loops	0.5 s: 150 loops
			1 s: 150 loops	2 s: 150 loops
			CJ1G-CPU42P (LCB01)

	Number of operations for process (excluding control)		LCB01: Max. 50 blocks LCB03: Max. 30 blocks
	Sequential control (Use only one or the other)	Step ladders	LCB01: Max. 20 blocks per Board and total max. 2,000 commands per Board LCB03: Max. 200 blocks per Board and total max. 4,000 commands per Board Loop Controllers common: Divisible to 100 commands max. per block and 100 steps max. per block (100 commands max. per step)
