#30 H’4050 ╳ R Error status Register for storing all error status.
See the table of error status for more information.
CR#30: Error status value (See the table below)
Error status Content b15 ~ b8 b7 b6 b5 b4 b3 b2 b1 b0
Abnormal power supply K1 (H’1)
Reserved
0 0 0 0 0 0 0 1
Incorrect analog input value K2 (H’2) 0 0 0 0 0 0 1 0
Incorrect mode setting K4 (H’4) 0 0 0 0 0 1 0 0
OFFSET/GAIN error K8 (H’8) 0 0 0 0 1 0 0 0
Memory self-test fail K16 (H’10) 0 0 0 1 0 0 0 0
Abnormal digital range K32 (H’20) 0 0 1 0 0 0 0 0
Incorrect average times setting K64 (H’40) 0 1 0 0 0 0 0 0
Instruction error K128 (H’80) 1 0 0 0 0 0 0 0
Note: Each error status is determined by the corresponding bit (b0 ~ b7) and there may be more than 2 errors occurring at the
same time. 0 = normal; 1 = error.
Example: If the digital input exceeds 4,000, error (K2) will occur. If the analog output exceeds 10V, both analog input value
error K2 and K32 will occur.
#31 H’4051 ○ R/W Communication address For setting up RS-485 communication address.
Range: 01 ~ 254. Default = K1
#32 H’4052 ○ R/W Communication format
6 communication speeds: 4,800 bps /9,600 bps /19,200 bps /
38,400 bps /57,600 bps /115,200 bps. Data formats include:
ASCII: 7, E, 1/ 7,O,1 / 8,E,1 / 8,O,1 / 8,N,1 / 7,E,2 / 7,O,2 /
7,N,2 / 8,E,2 / 8,O,2 / 8,N,2
RTU: 8, E, 1 / 8,O,1 / 8,N,1 / 8,E,2 / 8,O,2 / 8,N,2
Default: ASCII,9600,7,E,1(CR#32=H‘0002)
Please refer to✽CR#32 at the bottom of the page for more
details.
#33 H’4053 ○ R/W
Return to default;
OFFSET/GAIN tuning
authorization
Reserved CH4 CH3 CH2 CH1
Default = H’0000. Take the setting of CH1 for example:
1. When b0 = 0, the user is allowed to tune CR#18
(OFFSET) and CR#24 (GAIN) of CH1. When b0 = 1, the
user is not allowed to tune CR#18 (OFFSET) and CR#24
(GAIN) of CH1.
2. b1 represents whether the OFFSET/GAIN tuning registers
are latched. b1 = 0 (default, latched); b1 = 1 (non-latched).
3. When b2 = 1, all settings will return to default values.
(except CR#31, CR#32)
CR#33: For authorizations on some internal functions, e.g. OFFSET/GAIN tuning. The latched function will store the
output setting in the internal memory before the power is cut off.
#34 H’4054 ○ R Firmware version Displaying the current firmware version In hex; e.g. version
1.0A is indicated as H’010A.
#35 ~ #48 For system use.
Symbols:
○:Latched (when written in through RS-485 communication);
╳: Non-latched;
R: Able to read data by FROM instruction or RS-485 communication;
W: Able to write data by TO instruction or RS-485 communication.
LSB (Least Significant Bit):
For voltage output: 1LSB = 10V/4,000 = 2.5mV. For current output: 1LSB = 20mA/4,000 = 5μA.
