Abbr.
PV This value can be set when scan is Off (SCN = 1). When application
program is used to correct PV (PV<>PVC), PV is open to application
program.
SCN Standard input processing is stopped when SCN = 1 and standard input
processing is executed when SCN = 0.
SIM Simulation is specified when SIM = 1 and simple loop-back of MV
will be executed.
SPR The following alarms will be reset when SPR is 1: PVH, PVL, PVD, PVI
and PRE
RST Initialization of TTL tag integrated value will be executed when RST = 1. BOOL
PDE I/O module error. An ADC error or module down is generated.
PVI Input signal error. Broken wire or an error of sensor (out of range)
occurred. For condition of PVI generation, refer to Signal type code
(SIG).
PRE Either a device error (PDE) or a sensor error (PVI) occurred. PRE is
used to monitor PV of its own and temperature/pressure correction PV
using PV error processing definition (PRD).
PVH PV has exceeded PH.
PVL PV is less than PL.
PVD PV rate-of-change has exceeded DPL.
DEU Unconfirmed bit of each error. When "LDU alarm restoration method"
for LC5** module parameter is a confirmed restoration method, this is
used as unconfirmed bit. This is not used in auto restoration.
