Operating Procedure Guidelines
Section 1-5
Depending on the Output Control Mode, Counter Range or Comparison Data
can be set. For each Counter, up to a maximum of 4 Ranges or 8 Comparison
Values can be assigned. You can set the Range or Comparison Data in a part
of DM or EM which is not being used. If you only intend to use a limited num-
ber of Ranges or Comparison Values then it is also possible to use the work-
words of the Special I/O Unit DM-Area to store the Range or Comparison
Data (287 work-words for the CJ1W-CTL41-E are available). Therefore, at the
end of every block with Counter Specific Settings, you can specify an Indirect
Address. This Indirect Address points to the actual memory location where
the Range- or Comparison Settings of that specific Counter are stored.
For a detailed description about the CIO- and DM-Memory Allocation refer to
section
.
Note
During operation of the Unit, for Circular and Linear Counters run-time config-
uration is possible by using the IOWR-instruction from the PLC Ladder Pro-
gram (refer to section
4-5 Supported IOWR/IORD-Instructions
). Additionally,
Outputs can be configured to generate interrupts to the PLC by setting the
appropriate Interrupt Masks in DM. (refer to section
1-5
