Setting Procedures For Data Obtaining Conditions - Omron ZS Command Reference Manual

Setting Procedures for Data Obtaining Conditions

Follow the procedures below to set the data obtaining conditions:
Note that setting conditions described in this section are cleared upon turning OFF the
power of the controller. (Set the threshold values again.)
The all data obtaining conditions set here are written using the parameter area write
command. When setting, refer to the corresponding tables in "Unit No." and "Data No.",
command examples described in Section 3, and the description of the parameter area
write in Section 2.
1.
Set the accumulation mode to ON.
Set the flow data accumulation mode to ON (=1). Make sure to set this value
to ON (or write 1 to this value) in advance of obtaining data because flow
data is not accumulated unless this setting is made. Specifically, write ON
(=1) to Data No. 2 of Unit No.124 (=7Ch). (*)
Example: When writing the above command to ZS-MDC (0CH), a command
to be sent is shown as below:
02h 02h C002h 7C00h 8001h 00000001
(*)
A measurement cycle changes from 112 microseconds to 142 microseconds
upon setting the accumulation mode to ON when the ZS-LDC is used in the
high speed mode. That is to say, the LDC itself as a single unit cannot obtain
measurement data at every 112 microseconds via communications. To
obtain the measurement data at every 112 microseconds, use a composition
of ZS-LDC and ZS-MDC to obtain the measurement data from ZS-LDC via
ZS-MDC.
