Description of Operation Section 3-2
(3) Calibration mode will be exited and calculation will stop if calculation is
stopped from calibration mode. Thereafter, even if the calculation stop
status is cleared, operation will start in normal mode and will not return to
calibration mode. To return to calibration mode, switch the operation
mode again.
(4) During calibration mode, performing a hot start or cold start, turning ON
the power, or restarting the Inner Board will cancel calibration mode.
Monitoring Actual PV
Input
When using LCB Ver. 3.0, the real PV input of the function block for calibration
mode is always (whether in calibration mode or normal mode) output to the
real PV input monitor area. (See note.)
Note (1) The actual PV input monitor area is allocated in EM
@_29020+N-1 (@ in-
dicates the EM Bank No. and N indicates the block address (1 to 500)).
(2) When calibration mode is not enabled for the function block, 0 will be out-
put to the actual PV input monitor area.
3-2-13 Relationship between CPU Unit States and Loop Controller States
Conditions for
stopping and
continuing running
Running of the Loop Controller is stopped or continued under the following
conditions.
Note The High Load Alarm Flag (A42408) turns ON if the LCB load rate exceeds
80% three times consecutively. The Loop Controller will continue operation.
(For details, 3-2-17 About the LCB Load Rate.)
Operation of the Loop
Controller at a CPU
Unit fatal error
When running of the CPU Unit has stopped due to a fatal error (including exe-
cution of the FALS command), running of the Loop Controller is also stopped.
Note Analog Output Units CS1W-PMV01/PMV02, Analog Output Units C200H-
DA003/004, CS1W-DA08V/C and CS1W-DA041 and Analog Input/Output
Units C200H-MAD01 and CS1W-MAD44 have a function (output hold func-
tion) for holding the analog output value to one of the previous value, mini-
mum value or maximum value when either of the following has occurred:
• Fatal error (including execution of the FALS command)
• Output OFF
For this reason, use this output hold function of the Analog Output Unit to hold
the analog output values to a specific value when running of both the CPU
Unit and Loop Controller has stopped.
Operation of the Loop
Controller when the
CPU Unit is in the
PROGRAM mode
The Loop Controller continues to run even if the CPU Unit is in the PRO-
GRAM mode.
Running stop conditions Running continuation conditions
• When the following malfunctions occur:
• Initial recognition error
• Unit error
• Function block database error (when all
function blocks are in error)
• CPU Unit error (WDT error, cyclic moni-
tor error, bus error)
• CPU of CPU Unit in standby mode
• CPU Unit fatal error (including execution
of FALS command)
• When the following malfunctions occur:
• Function block database error (when only a
specific function block is in error)
• CPU Unit non-fatal error (including execu-
tion of the FAL command)
• When CPU is in one of PROGRAM, RUN or
MONITOR modes
• When output of the CPU Unit is OFF (Output
OFF flag is ON)
