Setting the largest unit number for a PC(PLC) link
The largest unit number can be set using system register no. 47 (using system register no. 57 for
PC(PLC) link 1 (for FP
Σ
32k type only)).
[Sample setting]
No. of units linked
Setting contents
2
1st unit: Unit no. 1 is set
2nd unit: Unit no. 2 is set
A largest unit no. of 2 is set for each.
4
1st unit: Unit no. 1 is set
2nd unit: Unit no. 2 is set
3rd unit: Unit no. 3 is set
4th unit: Unit no. 4 is set
A largest unit no. of 4 is set for each.
n
Nth unit: Unit no. n is set
A largest unit no. of n is set for each.
Note:
•
Unit numbers should be set sequentially and consecutively, starting from 1, with no breaks between
them. If there is a missing unit number, the transmission time will be longer.
•
For all PLCs which are linked, the same value should be set for the largest unit number.
•
If there are fewer than 16 units linked and the largest unit number has not been set (default=16), or the
largest unit number has been set but the unit number settings are not consecutive, or the unit number
settings are consecutive but there is a unit for which the power supply has not been turned on, the
response time for the PC(PLC) link (the link transmission cycle) will be longer.
Reference:
<7.6.5 PC(PLC) Link Response Time>.
Setting PC(PLC) link switching flag (For FP
Σ
32k type only)
PC(PLC) link switching flag can be set using system register no. 46.
If it is set to 0 (default value), the first half of the link relays and registers are used. If it is set to 1, the
second half of the loink relays and registers are used.
