5.4.1 D Register Contents
D registers are designed to indicate two or more events, such as errors and parameter data, using
combinations of bits within them. If any of the events shown in the following tables occurs, the
corresponding bit is set to 1. The bit remains set to 0 if the event has not occurred yet. Note that bits
in blank fields are not in use.
●
D0001 Register - Bit Configuration of STATUS (Input Error)
Bit Code Event
0 ALM1.st ‘1’ if alarm 1 is on, or ‘0’ if off
1 ALM2.st ‘1’ if alarm 2 is on, or ‘0’ if off
2 0
3 0
4 PV+over.st PV above the upper limit of scale
5 PV-over.st PV below the lower limit of scale
6 BO.st Burn-out error
7 0
8 SYSTEM.E.st Error in system data
9 CALB.E.st Error in calibrated values
10 PARA.E.st Error in operating parameters
11 0 Error in automatical calibration of valve position
12 ADERR.st Error in A/D Converter
13 RJCERR.st RJC error in PV
14 EEP.E.st Error in EEPROM
15 0

D0002 Register - PV (Measured Input Value)
●
D0003 Register - CSP (Currently used Target Setpoint)
●
D0009 Register - TIM (Duration Time)
Example: The reading for one hours, 38 minutes and 57 seconds is given as 5.937 seconds.
●
D0010 Register - MOD (Limit Control Status)
Bit Code Event
0 0
1 EXD. st 0:Not extend, 1:Extend
2 OUT. st 0:Relay off/Lamp on, 1:Relay on/Lamp off
3 to 15 0
●
D0101 and D0102 Registers - A1 and A2 (Alarm or Timer Setpoints)
If either “23” or “24” is set in the AL1 and AL2 registers, the value is used as the setpoint for the
timer in units of seconds. If a value other than “23” and “24” is set, it is used as the alarm setpoint.
●
D120 Register-CSP1 (Target Setpoint for writing via Communication Only)
The CSP1 parameter is a target setpoint for use via communication only and is effective only if the
SP1 parameter is selected. Use this register when you want to change the target setpoint by means
of communication. Once you write a value into this register, the D0114 (SP1) register contains the
same value. Note that data in the D0120 register is not recorded when the power is turned off.
When the power is turned back on, the D0120 register contains the value previously written into the
D0114 (SP1) register.
