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

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 10 ms duration or Set in increments of 1 ms.
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.
Port Settings
The
Peripheral Port, Comms Board A
,
Comms Board B
and
Host Link Port
tabs of the PLC Setup component
defines the settings for the connection between the PC and PLC. The default settings may be used or an alternative
communications protocol defined. Use the following procedure to apply settings.
1, 2, 3…
1. The
Port Settings
are set to 9600 bps, 1 start bit, 7-bit data, 2 stop bits and Even parity.
Customised port settings can be entered by deselecting the
Default
setting. The
Mode
setting can be set to one of the following connection types:
♦
PC.
♦
Hostlink 1 to n
. Multiple PLC RS422/485 connections to the PC.
♦
RS232C
. Single PLC RS232 connection to a printer or from a reader.
♦
1-to-1 Link Slave
. Sets PLC as slave in an RS232 PLC to PLC connection.
♦
1-to-1 Link Master
. Sets PLC as master in an RS232 PLC to PLC connection.
♦
NT Link 1:1
. For using NT link commands in an RS232 PLC to PT (Programmable Terminal)
connection.
♦
NT Link 1:n
. For using NT link commands in an PLC to RS422/485 multi-PT connection.
♦
Protocol Macro 1:1
. Single PLC RS232 to device connection.
♦
Protocol Macro 1:n
. PLC to RS422/485 multi-device connections.
2. Select
the
CTS Control
setting to enable use of the CTS line on the PLC.
3. Set
the
Unit Number
setting for the selected PLC.
4. Set
the
Delay
setting; a pre-set transmission delay in the range 0000 to 9999 (for BCD this
is in 10ms units).
The following entries cannot be amended:
♦
Link Words
. These word addresses are fixed at LR00 to LR63 (or bit addresses from LR0000 to LR6315).
♦
Start Code
and
End Code
. The message start and end codes.
♦
NT Link Max
.
Error Settings
The
Error Settings
tab of the PLC Setup component defaults to the detection and reporting of long cycle times,
interrupt errors and low battery condition. Use the following procedure to apply settings in the
Error Settings
tab.
1, 2, 3…
1.
Cycle Time
- Check the
Do not detect long cycles
option to stop detection and reporting of
long cycles.
2.
