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.
High Speed Counters
The CQM1H-CTB41 high-speed counter board is an Inner Board applicable to units CPU51 and CPU61. A
maximum of two boards can be mounted simultaneously in slots 1 & 2 of the PLC. The high-speed counter
board counts high-speed pulses from 50 to 500kHz entering through ports 1 to 4. It performs tasks according to
the number of pulses counted.
When the present value of the high-speed counter matches a specified target value or lies within a specified
range, the bit pattern specified in the comparison table is stored in internal output bits and external output bits.
A bit pattern can be set for each comparison result and the external output bits can be output through an external
output terminal.
Up to four external outputs can be produced when either the target value is matched or a range comparison
condition is satisfied. The high-speed counter board does not provide high-speed counter interrupts, it simply
compares the present value to target values or comparison ranges and produces internal and external bit outputs.
CPM1/CPM1A PLCs have a high-speed counter function that can be used in incrementing mode or up/down
mode. The high-speed counter can be combined with input interrupts to perform target value control or zone
