Output signal range 00: –10 to 10 V
01: 0 to 10 V
10: 1 to 5 V/4 to 20 mA (See note 2.)
11: Same as for setting “10” above.
Output status when
stopped
00: CLR 0 output
01: HOLD Hold output prior to stop
02: MAX Output maximum value of range
Loop
Ratio conversion use
designation
00: Do not use.
01: Use positive gradient conversion.
10: Use negative gradient conversion.
11: Same as for setting “10” above.
A constant 4 digits BCD (0 to 9999)
B constant 16-bit binary data
Note 1. For the DM word addresses, m = 1000 + 100 x unit number (Units #A to #F =
Unit numbers 10 to 15).
2. The I/O signal range of “1 to 5 V” or “4 to 20 mA” is switched according to the
input or output terminal connections.
