4-3 SR Area

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.

Word(s) Bit(s) Function Read/
write
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).)

(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 High-speed Counter PV Area
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.)
