10 / 22 page A--161 Programmable Controller CQM1H Memory Area Structure Data area Size Words Bits Function IR area Input area 256 bits IR 000 to IR 015 IR 00000 to IR 01515 Input bits are allocated to Input Units or Dedicated I/O Units. The 16 bits in IR 000 are always allocated to the CPU’s built-in in- puts. Bits in IR 001 to IR 015 are allocated to I/O or Dedicated I/O Units connected to the CPU. IR area Output area 256 bits IR 100 to IR 115 IR 10000 to IR 11515 Output bits are allocated to Output Units or Dedicated I/O Units connected to the CPU. Work areas 2,528 bits min. IR 016 to IR 089 IR 01600 to IR 08915 Work bits do not have any specific function and they can be free- ly used within the program. a eas IR 116 to IR 189 IR 11600 to IR 18915 y used t t e p og a (A minimum 2,528 bits are available as work bits. Most bits in the IR and LR areas can be used as work bits when they are not IR 216 to IR 219 IR 21600 to IR 21915 IR and LR areas can be used as work bits when they are not used for their allocated functions, so the total number of avail- able work bits depends on the configuration of the PLC.) IR 224 to IR 229 IR 22400 to IR 22915 Controller Link status areas 96 bits IR 090 to IR 095 IR 09000 to IR 09515 Status Area 1: Stores the Controller Link data link status information. status a eas IR 190 to IR 195 IR 19000 to IR 19515 Status Area 2: Stores the Controller Link error and network participation information. MACRO operand Input area 64 bits IR 096 to IR 099 IR 09600 to IR 09915 Used when the MACRO instruction, MCRO(99), is used. ope a d area Output area 64 bits IR 196 to IR 199 IR 19600 to IR 19915 Inner Board slot 1 area 256 bits IR 200 to IR 215 IR 20000 to IR 21515 These bits are allocated to the Inner Board mounted in slot 1 of a CQM1H-CPU51/61. High-speed Counter Board: IR 200 to IR 213 Serial Communications Board: IR 200 to IR 207 Analog settings area 64 bits IR 220 to IR 223 IR 22000 to IR 22315 Used to store the analog settings when a CQM1H-AVB41 Analog Setting Board is mounted. High-speed Counter, 0 PV 32 bits IR 230 to IR 231 IR 23000 to IR 23115 Used to store the present values of high-speed counter 0. Inner Board slot 2 area 192 bits IR 232 to IR 243 IR 23200 to IR 24315 These bits are allocated to the Inner Board mounted in slot 2. High-speed Counter Board: IR 232 to IR 243 Absolute Encoder Interface Board: IR 232 to IR 239 Pulse I/O Board: IR 232 to IR 239 Analog I/O Board: IR 232 to IR 239 SR area 184 bits SR 244 to SR 255 SR 24400 to SR 25507 These bits serve specific functions such as flags and control bits. HR area 1,600 bits HR 00 to HR 99 HR 0000 to HR 9915 These bits store data and retain their ON/OFF status when pow- er is turned OFF or when the operating mode is changed. AR area 448 bits AR 00 to AR 27 AR 0000 to AR 2715 These bits serve specific functions such as flags and control bits. TR area 8bits — TR 0toTR7 These bits are used to temporarily store ON/OFF status at pro- gram branches. LR area 1,024 bits LR 00 to LR 63 LR 0000 to LR 6315 Used for 1:1 data link through the RS-232 port or through a Controller Link module. Timer/Counter area 512 bits TIM/CNT 000 to TIM/CNT 511 (timer/counter numbers) The same numbers are used for both timers and counters. Timer numbers 000 to 015 can be used with TIMH(15) for inter- rupt-refreshed PVs to ensure proper timing without inaccuracy being caused by the cycle time. (This table continues on the next page.) |
