Output update time of CH4
118 O R/W
LV output mode setting
Set the output mode of CH1~CH4 when the power is at LV (low voltage)
condition. Default= H’0000.
Symbols:
O: When CR#41 is set to H’5678, the set value of CR will be saved.
X: Set value will not be saved.
R: You can use FROM instruction to read data.
W: You can use TO instruction to write data.
※ CR#0 for module reset
You can use CR#0 to reset all the settings by simply writing H’4352 in CR#0 and wait for one second before turning the
power OFF and then ON again, all the modules connected will be initialized. It is suggested to connect to only one module
for module reset. And this is only available for firmware V1.12 or later.
※ CR#43: Error status value. See the table below:
bit0 K1 (H’1) Power supply error bit11 K2048 (H’0800)
Upper / lower bound setting
Set value changing prohibited
bit2 K4 (H’4) Upper/lower bound error bit13 K8192 (H’2000)
Communication breakdown on
next module
Note: Each error status is determined by the corresponding bit (b0 ~ b13) and there may be more than 2 errors
occurring at the same time. 0 = normal; 1 = error
Adjust D/A Conversion Curve
You can adjust the conversion curves according to the actual needs by changing the Offset value (CR#28 ~ CR#31) and
Gain value (CR#34 ~ CR#37).
Offset: The corresponding voltage/current input value when the digital output value = 0.
Gain: The corresponding voltage/current input value when the digital output value = 16,000.
