(d) Forced on/off timing
(e) Number of registerable devices
Up to 32 devices in total can be registered.
(f) Checking the execution status
• Reading the forced on/off registration status of a programming tool.
• Flashing of the MODE LED (green) (The MODE LED flashes in green when a device is registered.)
• The on status of the 1st bit in SD840 (Debug function usage).
When checking by the MODE LED or SD840, remind that they are also used to check the execution status of executional
conditioned device tests. (
(g) Forcibly turning on/off from multiple programming tools
Forced on/off can be registered to a single CPU module from multiple programming tools. In this case, the last
registration is effective. For this reason, the forced on/off status which is different from the status actually
registered in the CPU module may be displayed on the screen that registered forced on/off earlier. When the
forced on/off registration is performed from multiple programming tools, click the
button to
update the data, and execute the function.
(h) Status of devices after forced on/off registration data are canceled
Refresh area
Timing
• Input and output used in the built-in I/O
function.
• Input and output of modules connected
• During END processing (input refresh)
• At execution of the COM instruction (input refresh)
• At execution of an instruction using direct access input (DX) and direct access output
(DY)
• At execution of the RFS or MTR instruction
• At execution of an instruction used for a system
Input and output of the CPU module to be
refreshed from RX/RY of a CC-Link module
• During END processing (auto refresh)
• At execution of the COM instruction (auto refresh)
• At execution of the ZCOM instruction (auto refresh)
Forced on/off registered device
Program operations (on/off)
performed
Program operations (on/off) not
performed
Input
• Input used in the built-in I/O function
• Input from connected modules on the base unit
Uses the on/off status input from modules.
Input of the CPU module to be refreshed from RX
of a CC-Link module
Uses the on/off status refreshed via CC-Link.
Output other than above (outside of the refresh
range)
Uses the results of program operations.
Holds the forced on/off status.
Output
• Output used in the built-in I/O function.
• Output from connected modules on the base
unit.
Outputs the results of program operations.
Holds the registered on/off status.
Output of the CPU module to be refreshed from
RY of a CC-Link module
Output other than above (outside of the refresh
range)
Outputs the results of program operations. (The
results are not output externally.)
Holds the forced on/off status.
