Message Communications Functions
The FINS commands listed in the table above can also be transmitted through
the network from other PLCs to the CPU Unit. Observe the following points
when transmitting FINS commands through the network.
FINS commands are sent with CMND(490) from the CPU Unit’s program.
Refer to the CPU Bus Unit’s Operation Manual for more details on the mes-
sage communications functions.
6-2 Analog Adjuster and External Analog Setting Input
6-2-1 Analog Adjuster
By turning the analog adjuster on the CP1H CPU Unit with a Phillips screw-
driver, the PV in the Auxiliary Area (A642) can be changed to any value within
a range of 0 to 255. During the adjustment, the value is displayed from 00 to
FF (hex) on the 7-segment LED display regardless of the CP1H operating
mode.
Application Example Setting the value for timer T100 in A642 makes it possible to use T100 as a
variable timer with a range of 0 to 25.5 s (0 to 255). A change in the set value
is reflected with the next scan.
Note Set values from the analog adjuster may vary with changes in the ambient
temperature and the power supply voltage. Do not use it for applications that
require highly precise set values.
