1, 2, 3… 1. Check the Watch Cycle Time setting and set the watch cycle time if enabled for the PLC;
the default is 0 ms.
2. Deselect the Set Time to all Events setting to enter a time period for all event processes; this
is entered as a percentage of the total cycle time.
3. Check the Power Off Interrupt setting, and set if enabled for the PLC; the default is 0ms.
4. Set the Cycle Time setting to define the time interval for cycles.
5. Set the Scheduled Interrupt Interval setting to schedule interrupts to occur at regular
intervals; either every 10 ms or a specific value can be set.
SIOU Refresh
The SIOU Refresh tab of the PLC Setup component allows SIOU Status to be enabled. Check the required Enable
SIOU Status setting for each SIOU in the field.
Unit Settings
The Unit Settings tab of the PLC Setup component allows timings for the individual rack slots associated with the
PLC to be set. Select the required slot(s) from the rack field and the required unit setting; the default is 8 ms.
Host Link Port
The Host Link Port tab of the PLC Setup component defines the protocol which allows transferring data between
the PLC and the host PC. The default settings may be used or an alternative communications protocol defined.
Some of the options may not be applicable depending on the device type selected. Use the following procedure to
apply settings in the
Host Link Port tab.
1, 2, 3… 1. The Port Settings default is 9,600 bps, 1 start bit, 7-bit data, 2 stop bits and Even parity.
Customised port settings can be entered by deselecting the Default setting.
2. Select the CTS Control setting to enable use of CTS.
3. Set the Unit Number setting for the selected PLC.
4. Set the Delay value; a pre-set transmission delay in the range 0000 to 9999 (for BCD this is
in 10 ms 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 .
Peripheral Port
The Peripheral Port tab of the PLC Setup component defines 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 in the
Peripheral Port tab.
1, 2, 3… 1. The Port Settings default 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.
2. Set the Unit Number setting for the selected PLC.
The NT Link Max setting cannot be amended.
Peripheral Service
Note that this tab is only available for the CS1-H and CJ1-H PLCs (CS1G-H, CS1H-H, CJ1G-H and CJ1H-H).
The tabbed dialog is split into three sections as follows:
Sync/Async Comms
Execution Mode - The default for this option is Not Specified, and as such means that all other parts are disabled
except for Set time to all events.
Select one option from the list to set the execution mode. Choosing Not Specified will disable all the options
within the Peripheral Service dialog, except for 'Set time to all events'. Not Specified is the only way of setting the
Peripheral Service Execution Time to zero.
