LCB01/05 Version 2.0 is supported by the easy backup function for data for
specified Units and Boards of the CS1-H CPU Unit. The function block data in
Loop Control Board RAM can be easily backed up in the same ways as data
from Motion Control Units, Position Control Units, and DeviceNet Units.
The simple backup function can back up, recover, and verify all PLC data,
including data for Loop Control Boards. This simplifies the task of replacing
damaged Boards or making copies of entire PLC-based process control sys-
tems.
The tag settings, comments, and user link table connection data created using
the CX-Process Tool can be backed up on PLC Memory Card. This means
that tag data and other settings do not have to be reset when it is uploaded
from PLC Memory Card using the CX-Process Tool.
With the previous version of the reference input function, Y1 was output start-
ing from the first set value that matched reference input X1. The enhanced
version offers a choice so you can specify whether to start from the first or
second set value that matches the reference input.
An error occurred with the original function if there was no match. With the
enhanced function, the program can be started from B0 (default setting) when
there is no match.
A Segment Program (Block Model 156) was used originally to synchronize
time axes when there was more than one Segment Program and, for example,
it was necessary to use the same PV start time. The data for time axis output
Y2 for one Segment Program had to be written to the time axis output for the
other Segment Programs using ITEM write blocks. This took up valuable Seg-
ment Program space because each program has only 15 program steps.
The enhanced version of Segment Program 2 (Block Model 157) has a func-
tion for synchronizing Segment Programs. With more than one Segment Pro-
gram 2, you can designate one to be the master to provide a reference time
axis and the others to be slaves who follow the master's time axis. Segment
Program 2 slaves do not calculate their own time axis and can be synchro-
nized to the time axis of the Segment Program 2 master. This enables other
program settings to be easily synchronized and started at the PV start point
for one measurement when using programmed temperature settings for multi-
ple zones or programmed temperature and pressure settings.
As long as the super capacitor did not discharge, hot starts were performed in
the past when the power was turned ON if the power was turned OFF less
than 24 hours and hot start was selected as the START mode.
The newly added START mode performs a hot start when the power is turned
ON only if it has been OFF for a specified amount of time (specified time for
hot start). With this mode selected, a hot start is always performed as long as
the power is OFF for less than the specified amount of time (within one hour).
This function enables selecting either a hot start or a cold start depending on
how long the power supply has been OFF (as long as it has been OFF for less
than an hour). If the power is OFF for longer than the specified amount of
time, then a cold start is performed when the power is turned ON.
