CHAPTER 4 – PLC Setup Component
CX-Server PLC Tools_ Page 35
Expansion Instructions
Set to either Default or User Settings. This option is only available for SRM1, CPM2* PLCs.
CompoBus/S Devices (CPM2*-S*)
Select the Maximum number of CompoBus and S Devices to either 16 or 32.
Communications Mode (CPM2*-S*)
Sets the communications mode to either High-Speed or Long-distance.
Memory Error on Capacitor Failure
Select this option if a memory error on capacitor failure is to be recorded.
Cycle Time
The
Cycle Time
tab of the PLC Setup component allows the total cycle time for the CPU unit to be defined.
This period is the time taken to complete monitoring, program execution and IO port servicing. Use the
following procedure to apply settings in the
Cycle Time
tab.
1, 2, 3…
1.
Cycle Monitor Time
setting. This option sets the time allowed for the CPU unit to cycle
through the type of operations indicated above. If it is exceeded, an error is generated
and the CPU unit is stopped.
2.
Cycle Time
setting. Use this option to define a minimum cycle time by selecting a time
period in the range 1 to 9,999ms. The default is
Variable
(with the CPU calculating the
cycle time in each cycle).
3.
Servicing Time
setting. This option allows the percentage of the defined cycle time
which can be used to service a port to be set. It can be set for the Peripheral Port,
RS232C Port, Comms Port A and Comms Port B.
Note:
The
Cycle Time
setting is ignored if the
Cycle Monitor Time
setting is longer and vice
versa (provided a minimum time has been defined). The CPU unit waits until the
longer of the two time periods has elapsed before starting the next cycle.
Interrupt/Refresh
The
Interrupt/Refresh
tab of the PLC Setup component allows certain PLCs to interrupt the main program by
input and scheduled interrupts in order to call a subroutine. Use the following procedure to apply settings in the
Interrupt/Refresh
tab.
1, 2, 3…
1.
Interrupt Response
- Set the interrupt mode to
High Speed
to interrupt immediately or to
Normal
to wait for the current process to complete.
2.
SIOU Refresh
setting - This option must be set to
Disable Refresh
when the
Interrupt
Response
setting is set to
High Speed
(if the
Disable Refresh
setting has been set and the
Interrupt Response
is set to
Normal
, the
Disable Refresh
setting is ignored).
3.
Schedule Interrupt Unit
setting - These are interrupts for which you can select regular
intervals of either a fixed 10ms duration or Set in increments of 1ms.
4.
SIOU Cyclic Refresh
setting - Set the
SIOU Cyclic Refresh
setting if required. An SIOU
Cyclic Refresh Unit(s) must be specified if an SIOU refresh setting has been made.
The CQM1 PLCs support input and scheduled interrupts to stop the main program to run a subroutine.
The following Interrupt/Refresh options are available with the CQM1H.
5.
Interrupt Enable
– This option allows you to set the various IR value interrupts to either:
Normal (default), Interrupt or Quick.
6.
Input Constant
- This option allows you to set the input constant of IR000 Bits. Select
the value in milliseconds as appropriate.
7.
Pulse Output 0/1 Unit
– Set the output pulse 0 and 1 to either Relative or Absolute.
