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 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. Styles - Check the Do not store records option if records are not to be stored.
3. Battery - Check the Do not detect low battery option if low battery condition is not to be
reported on.
