Refreshing of analog outputs is set in the Unit Setup Area (DM 6630 bits 00 to 07 for
both ports) to one of the following:
END refresh
Immediate refresh via SPED or ACC execution
END refresh If the Analog Output Conversion Enable Bit is ON (port 1: AR 1600,
port 2: AR 1601), the value in AR 14 or AR 15 is output after pro-
gram execution.
Immediate If the Analog Output Conversion Enable Bit is ON, the specified ana-
refresh via log value is output when the instruction is executed in the program.
instructions
SPED: Analog output varied stepwise
ACC: Analog output with up or down slop (every 2 ms)
Note 1: Analog output values can also be controlled from interrupt
subroutines.
Note 2: The value of the analog outputs from startup until an
instruction controlling the analog output is executed will be as set for
the analog output hold function.
For END refresh, the values in AR 14 and AR 15 are output.
For immediate refresh via instructions, the following values are output according to the
operands of the instruction.
–10 to 10 V: EC78 to 1388 Hex (–5,000 to 5,000 decimal) (resolution: 10,000) corre-
sponding to 0% to 100% voltage (–10 to 10 V) (Actually, the setting range is EA84 to
157C (–5,500 to 5,500 decimal) corresponding to –5% to 105% voltage (–11 to 11 V)
0 to 10 V, 0 to 5 V, or 1 to 5 V: 0000 to 0FA0 Hex (0000 to 4,000 decimal) (resolution:
4,000) corresponding to 0% to 100% of the FS range. (Actually, the setting range is
FF38 to 1068 (–200 to 4,200 decimal) corresponding to –5% to 105% voltage (–0.5 to
10.5 V, –0.25 to 5.25 V, or 0.8 to 5.2 V)
Port 1: AR 14, port 2: AR 15
For END refresh, the value on the END refresh. If the hold function is used, however, to
clear or to output the peak value, the actual output value may be different.
For immediate instruction refreshing, the value specified for output by SPED or ACC is
stored in these words. If the hold function is used, the values output for the hold function
are stored.
12 mA
±0.3% of FS
±0.5% of FS
The ACC instruction can be used to change the analog output value at the following
rates:
–10 to 10 V: 0000 to 2AF8 Hex (0 to 11,000 decimal)
0 to 10 V, 0 to 5 V, or 1 to 5 V: 0000 to 1130 Hex ( 0 to 4,400 decimal)
The output value is cleared, held at peak value, or held at the current value for the fol-
lowing.
Analog Output Conversion Enable Bit (port 1: AR 1600, port 2: AR 1601) turns OFF.
Analog Output SV Error Flag (port 1: AR 1708, port 2: AR 1709) turns ON.
Fatal error occurs for the Customizable Counter Unit (except for Customizable Counter
Unit WDT error or flash memory adjustment data error). (See note 2.)
The other analog output if one output is being adjusted in adjustment mode.
The output values can be offset as required by the connected device.
In Adjustment Mode (set in DM 6631 of the User Setup Area for both ports), the offset
or gain can be specified and changed by manipulating the Up and Down Bits from a
Programming Device while the Adjustment Enable Bit (port 1: AR 1800, port 2: AR
1801) is ON.
Offset values: –10 to 10 V: FE0C to 01F4 Hex
0 to 10 V, 0 to 5 V, or 1 to 5 V: FF38 to 00C8 Hex
Gain values: –10 to 10 V: 1194 to 157C Hex
0 to 10 V, 0 to 5 V, or 1 to 5 V: 0ED8 to 1068 Hex
