SR Area

Word(s) Bit(s)
SR 228, 00 to 15 Pulse Output PV 0
SR 229 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, 00 to 15 Pulse Output PV 1
SR 231 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 00 to 15 Macro Function Input Area
to Contains the input operands for MCRO(99).
SR 235 (Can be used as work bits when MCRO(99) is not used.)
SR 236 00 to 15 Macro Function Output Area
to Contains the output operands for MCRO(99).
SR 239 (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 Not used.
SR 243
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 Not used.
SR 247
SR 248, 00 to 15 High-speed Counter PV Area
SR 249 (Can be used as work bits when the high-speed counter is not used.)
SR 250, 00 to 15 Not used.
SR 251
92
These bits mainly serve as flags related to CPM2C-S 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.
