Item
Description
Counter CH
Set the counter CH of coincidence output target.
Comparison Type
Set comparison type.
Output Destination Device
Sets output destination device for output comparison
results of comparison value 1 and comparison value 2.
Comparison Value 1
Sets the specification method of comparison value 1.
Specification Method
Comparison Value 1 Direct
Sets value (comparison value 1) to be compared with
current value of high-speed counter. (When direct
specification is selected)
Comparison Value 1 Indirect
Sets device (comparison value 1) to be compared with
current value of high-speed counter. (When indirect
specification is selected)
*1 The number in  is first module: 9, second module: 11, third module: 13, fourth module: 15.
• You can create an open table entry before table setting is complete.
• Table settings can be made in any order. Be careful when the current value is changed by self-reset at a
table along the way, as table processing starts with the first table then the following tables in order.
High-speed comparison table operation
Operation of each type of high-speed comparison table operation is explained below.
■Set to ON
When comparison value 1 matches the current value of the set high-speed counter, the bit device specified as the output
destination device is set. If interrupt pointer has been specified for output destination device, the interrupt program of the
specified interrupt pointer is run simultaneously when it matches comparison value 1.
Operation is the same as for the DHSCS instruction. For information on the DHSCS instruction, refer to MELSEC iQ-F
FX5 Programming Manual (Instructions, Standard Functions/Function Blocks).
■Reset
When comparison value 1 matches the current value of the set high-speed counter, the bit device specified as the output
destination device is reset.
Operation is the same as for the DHSCR instruction. For information on the DHSCR instruction, refer to MELSEC iQ-F
FX5 Programming Manual (Instructions, Standard Functions/Function Blocks).
