Omron CPM2B ユーザーズマニュアル

These bits mainly serve as flags related to CPM2A/CPM2C operation or contain
present and set values for various functions. The functions of the SR area are
explained in the following table.

Note “Read-only” words and bits can be read as status in controller PC operation, but

they cannot be written from the ladder program. Bits and words that are “Not
used” are also read-only.

SR 228,
SR 229

00 to 15

Pulse Output PV 0
Contains the pulse output PV (–16,777,215 to 16,777,215). SR 22915 acts as the sign
bit; a negative number is indicated when SR 22915 is ON.
(The same PV data can be read immediately with PRV(62).)

Only Pulse Output PV 0 is used for ACC(––).

SR 230,
SR 231

00 to 15

Pulse Output PV 1
Contains the pulse output PV (–16,777,215 to 16,777,215). SR 23115 acts as the sign
bit; a negative number is indicated when SR 23115 is ON.
(The same PV data can be read immediately with PRV(62).)

SR 232

SR 235

00 to 15

Macro Function Input Area
Contains the input operands for MCRO(99).
(Can be used as work bits when MCRO(99) is not used.)

SR 239

00 to 15

Macro Function Output Area
Contains the output operands for MCRO(99).
(Can be used as work bits when MCRO(99) is not used.)

SR 240

00 to 15

Interrupt Input 00003 Counter Mode SV
SV when interrupt input 00003 is used in counter mode (4 digits hexadecimal).
(Can be used as work bits when interrupt input 00003 is not used in counter mode.)

SR 241

00 to 15

Interrupt Input 00004 Counter Mode SV
SV when interrupt input 00004 is used in counter mode (4 digits hexadecimal).
(Can be used as work bits when interrupt input 00004 is not used in counter mode.)

SR 242

00 to 15

Interrupt Input 00005 Counter Mode SV
SV when interrupt input 00005 is used in counter mode (4 digits hexadecimal).
(Can be used as work bits when interrupt input 00005 is not used in counter mode.)

SR 243

00 to 15

Interrupt Input 00006 Counter Mode SV
SV when interrupt input 00006 is used in counter mode (4 digits hexadecimal).
(Can be used as work bits when interrupt input 00006 is not used in counter mode.)

SR 244

00 to 15

Interrupt Input 00003 Counter Mode PV
Counter PV when interrupt input 00003 is used in counter mode (4 digits hexadecimal).

SR 245

00 to 15

Interrupt Input 00004 Counter Mode PV
Counter PV when interrupt input 00004 is used in counter mode (4 digits hexadecimal).

SR 246

00 to 15

Interrupt Input 00005 Counter Mode PV
Counter PV when interrupt input 00005 is used in counter mode (4 digits hexadecimal).

SR 247

00 to 15

Interrupt Input 00006 Counter Mode PV
Counter PV when interrupt input 00006 is used in counter mode (4 digits hexadecimal).

SR 248,
SR 249

00 to 15

The PVs can have the following values. The leftmost digit of SR 249 acts as the sign
indicator; a negative number is indicated when the leftmost digit of SR 249 is F.

Differential phase input mode:

–8,388,608 (F838 8608) to 8,388,607

Pulse +direction input mode:

–8,388,608 (F838 8608) to 8,388,607

Up/down pulse input mode:

–8,388,608 (F838 8608) to 8,388,607

Increment mode:

0 to 16,777,215

Synchronized pulse control:

0 to 20,000 Hz

(Can be used as work bits when the high-speed counter is not used.)
