11 / 22 page A--162 Programmable Controller CQM1H Memory Area Structure -- continued from previous page Data area Size Words Bits Function DM area Read/ write 3,072 words DM 0000 to DM 3071 — DM area data can be accessed in word units only. Word values are retained when the power is turned OFF. e 3,072 words DM 3072 to DM 6143 — Available in CQM1H-CPU51/61 CPUs only. Read- only 425 words DM 6144 to DM 6568 — Cannot be written from the program (only from a Programming Device). DM 6400 to DM 6409: Controller Link parameters DM 6450 to DM 6499: Routing tables DM 6550 to DM 6559: Serial Communications Board Setup Error history area 31 words DM 6569 to DM 6599 — Cannot be written from the program (only from a Programming Device). Stores the time of occurrence and error code of errors that occur. PLC setup 56 words DM 6600 to DM 6655 — Cannot be written from the program (only from a Programming Device). Stores various parameters that control PLC operation. EM area 6,144 words EM 0000 to EM 6143 — EM area data can be accessed in word units only. Word values are retained when the power is turned OFF or the operating mode is changed. (CQM1H-CPU61 CPU Unit only.) Other Functions Item Specification Macro instructions Subroutines called by instructions containing arguments. Min. cycle time 1 to 9,999 ms (Unit: 1 ms) Cycle time monitoring When the cycle time exceeds 100 ms, the Cycle Time Over Flag turns ON, and operation continues. (A setting can be made in the PLC Setup so that this error is not generated.) When the cycle time exceeds the cycle monitor time, operation is stopped. Cycle monitor time settings: 0 to 990 ms in 10-ms units, 0 to 9,900 ms in 100-ms units, 0 to 99 s in 1-s units. The maximum and current values of the cycle time are stored in the AR area. I/O refreshing Cyclic refreshing, refreshing by IORF(97), direct output refreshing (set in the PLC Setup), interrupt input refresh- ing. (The inputs that are refreshed can be set separately for input interrupts, high-speed counter interrupts, and interval timer interrupts in the PLC Setup.) I/O memory status when changing operating mode Depends on the ON/OFF status of the I/O Hold Bit (SR 25212). Load OFF All outputs on Output Units can be turned OFF when the CPU is operating in RUN, MONITOR, or PROGRAM mode. (Used for stopping output in emergencies, for debugging, etc.) User-customized DIP switch setting A pin setting on the DIP switch on the front of the CPU is stored in AR 0712. This setting can be used as an ON/OFF condition (e.g., to switch between trial operation and actual operation). Mode setting at power-up Possible Debugging Forced set/reset, differential monitoring, data tracing (scheduled, cyclic, or when instruction is executed). Online editing User programs can be overwritten in program-block units when the CPU is in MONITOR mode. With the CX- Programmer, more than one program block can be edited at the same time. Program protection Write-protection of user program and data memory (DM 6144 to DM 6655: read-only DM): Set using pin 1 of the DIP switch. Error check User-defined errors (i.e., user can define fatal errors and non-fatal errors using the FAL(06) and FALS(07) in- structions.) (It is possible to stop operation using FALS(07) for fatal errors. User-defined error logs can be created in specific bits (logging) when using FAL(06). Error log Up to 10 errors (including user-defined errors) are stored in the error log. Information includes the error code, error details, and the time the error occurred. Serial communications Built-in mini-peripheral port: Programming Device (including Programming Console) connections, Host Links, no-protocol communications Built-in RS-232C port: Programming Device (excluding Programming Console) connections, Host Links, no-protocol communications, NT Links (1:1 mode), 1:1 Data LInks RS-232C port and RS-422A/485 port on Serial Communications Board (sold separately): Programming Device (excluding Programming Console) connections, Host Links, no-protocol communications, NT Links (1:1 mode, 1:N mode), 1:1 Data LInks, protocol macros (This table continues on the next page.) |
