#32 H’4084 O R/W
Communication baud
rate setting
For ASCII mode, date format is 7 bits,
even, 1 stop bit (7, E, 1), while RTU
mode, date format is 8 bits, even, 1 stop
bit (8, E, 1).
b0: 4,800 bps (bit/sec).
b1: 9,600 bps (bit/sec). (default setting)
b2: 19,200 bps (bit/sec).
b3: 38,400 bps (bit/sec).
b4: 57600 bps (bit/sec).
b5: 115,200 bps (bit/sec).
b6 ~ b13: Reserved.
b14: switch between low bit and high bit
of CRC code (RTU mode only).
b15: RTU mode.
b15~b12 b11~ b9 b8~b6 b5~b3 b2~b0

#33 H’4085 O R/W
Reset to default
setting
Example: Setting of CH1
1. b0 ~ b1: Reserved.
2. b2: Set to 1 and PLC will be reset to
default settings.
Definition of ERR LED: b12~b15=1111
(default settings)
1. b12 corresponds to CH1: when
b12=1, scale exceeds the range, ERR
LED flashes.
2. b13 corresponds to CH2: when
b13=1, scale exceeds the range, ERR
LED flashes.
3. b14 corresponds to CH3: when
b14=1, scale exceeds the range, ERR
LED flashes.
4. b15 corresponds to CH4: when
b15=1, scale exceeds the range, ERR
LED flashes.
#34 H’4086 O R Software version
Display the software version in
hexadecimal. ex: H’010A = version 1.0A
#35 ~ #48 System used
Symbols:
O: means latched. X: means not latched. (Support when using RS-485 communication, not
support when connecting with MPU)
R: able to read data by using FROM instruction or RS-485.
W: able to write data by using TO instruction or RS-485.
ϡ
The corresponding parameters address H’4064 ~ H’4086 of CR#0 ~ CR#34 are provided for
users to read/write data via RS-485 communication.
1. Function code: 03’H - read data from register. 06’H - write one word to register. 10’H -
write multiple words to registers.
2. CR#30 is the error code register. Refer to the chart below:

Note: Each error code will have corresponding bit (b0 ~ b7). Two or more errors may
happen at the same time. 0 means normal and 1 means having error.
