4-6 Analog Output Functions and Operating Procedures
4-6-1 Output Settings and Conversions
Output Numbers The Analog Output Unit converts only analog outputs specified by output
numbers 1 to 8 (output numbers 1 to 4 for CS1W-DA041). To specify the ana-
log outputs to be used, turn ON from a Programming Device the D(m) bits in
the DM Area shown in the following diagram.
Note There are only four outputs (1 to 4) for the CS1W-DA041.
The analog output conversion cycle can be shortened by setting any unused
output numbers to 0.
Conversion cycle = (1 ms) x (Number of outputs used)
Note 1. For the DM word addresses, m = D20000 + (unit number x 100).
2. Output numbers not used (set to 0) will be output at 0 V.
Item Contents
Output to be adjusted Sets output to be adjusted.
Leftmost digit: 1 (fixed)
Rightmost digit: 1 to 8 (1 to 4 for CS1W-DA041)
Offset (Offset Bit) When ON, adjusts offset deviation.
Gain (Gain Bit) When ON, adjusts gain deviation.
Down (Down Bit) Decrements the adjustment value while ON.
Up (Up Bit) Increments the adjustment value while ON.
Set (Set Bit) Sets adjusted value and writes to EEPROM.
Clr (Clear Bit) Clears adjusted value. (Returns to default status)
Conversion value for
adjustment
The conversion value for adjustment is stored as 16 bits
of binary data.
Alarm Flags Bit 12: Not used
