Appendix
The following table provides a quick reference to all RLL instructions supported by the
EZTouch I/O
Jr., as well as a brief description regarding the function of each instruction.
Instruction Description
Relay/Boolean Instructions
NO Contact When the corresponding memory bit is a 1 (on) it
will allow power flow through this element
NC Contact When the corresponding memory bit is a 0 (off) it
will allow power flow through this element
Positive Transition If the corresponding bit has changed from 0 (off) to
1 (on) in the current scan, power flows through
this element
Negative Transition If the corresponding bit has changed from 1 (on) to
0 (off) in the current scan, power flows through
this element
NO Coil As long as the power flows to the instruction,
corresponding memory bit remains 1 (on)
NC Coil As long as the power flows to the instruction,
corresponding bit to remains 0 (off)
Set Coil When power flows to the instructions,
corresponding bit is set to 1 (on) and remains 1
(on) even if the rung condition goes to false (Use
RESET COIL instruction to turn the corresponding
bit Off.)
Reset Coil
When power flows to the instructions,
corresponding bit is set to 0 (off) and remains 0
(off) even if the rung condition becomes false (Use
SET COIL instruction to turn the corresponding bit
On.)
NO Immediate Input PLC reads the addressed bit immediately from the
input module (instead of memory). The power
flows through the instruction if the read bit is 1
(on). (Please note all the bits corresponding to the
input module are updated with the read value.)
NC Immediate Input PLC reads the addressed bit immediately from the
input module (instead of memory). The power
flows through the instruction if the read bit is 0
(off). (Please note all the bits corresponding to the
input module are updated with the read value.)
NO Immediate Output The bit status is immediately written to
corresponding output module. The bit remains 1
(on) as long as the power flows to the instruction.
NC Immediate Output The bit status is immediately written to
