Description
y
When the ELC goes from STOP to RUN, set CH1 to current output mode (mode 3).
y
In the current mode for the ELC-AN04NANN, the range for 0 ~ 20mA is K0 ~ K4,000.
D0 is the current output value in ma, which is 1/200 of the actual output current digital
value (i.e. 20/4,000 = 1/200). Multiply the value in D0 by 200 and store the value
obtained into data register D40, which is sent to the ELC-AN04NANN for analog
output channel CH1.
