17.3 Command and Function Lists for 1C Frame
Use the following commands for data communication using 1C frame.
*1 Use the dedicated commands for extended registers to read/write extended file registers from/to ACPU.
*2 The devices for the five types of commands (BM, JM, WM, QM, EM) for registering monitor data can be registered simultaneously in
C24 for each interface.
ACPU common command, AnA/AnUCPU common command
ACPU common command is a communication function issued by MC protocol. The command is accessible for ACPU.
AnA/AnUCPU common command is a command for AnACPU and AnUCPU. The command cannot be executed for other
than AnA/AnUCPU.
: Executable, : Executable (with restrictions), : Not executable
When accessing modules other than ACPU, there is a restriction for the accessible device range.

Description
Device memory
*1
Batch read Bit units BR JR Reads bit devices (X, Y, M, etc.) in 1-point units.
Word units WR QR Reads bit devices (X, Y, M, etc.) in 16-point units.
Reads word devices (D, T, C, etc.) in 1-point units.
Batch write Bit units BW JW Writes bit devices (X, Y, M, etc.) in 1-point units.
Word units WW QW Writes bit devices (X, Y, M, etc.) in 16-point units.
Writes word devices (D, T, C, etc.) in 1-point units.
Test (random
write)
Bit units BT JT Set/reset devices and device numbers to bit devices (X, Y, M, etc.) by
specifying them randomly in 1 point unit.
Word units WT QT Set/reset devices and device numbers to bit devices (X, Y, M, etc.) by
specifying them randomly in 16 point units.
Write devices and device numbers to word devices (D, T, C, etc.) by
specifying them randomly in 1 point units.
Register
monitor data
*2
Bit units BM JM Registers bit devices (X, Y, M, etc.) to be monitored in 1-point units
Word units WM QM Registers bit devices (X, Y, M, etc.) to be monitored in 16-point units.
Registers word devices (D, T, C, etc.) to be monitored in 1-point units.
Monitor Bit units MB MJ Monitors the devices registered by monitor data registration.
Word units MN MQ
Extended file
register
Batch read ER Reads extended file register (R) in 1-point units.
Batch write EW Writes extended file register (R) in 1-point units.
Direct read Word units NR Read data in 1 point units by specifying the consecutive device number
regardless of the block number of extended file register.
Direct write Word units NW Write data in 1 point units by specifying the consecutive device number
regardless of the block number of extended file register.
Test (Random write) ET Write block numbers and device numbers to extended file register (R) by
specifying them randomly in 1 point units.
Register monitor data
*2
EM Register extended file register (R) in 1-point units.
Monitor Word units ME Monitor the extended file register (R) registered by monitor data
registration.
Special function
module
Batch read TR Reads data in the buffer memory of a special function module.
Batch write TW Writes data to the buffer memory of a special function module.
Loopback test TT Send (returns) characters received from an external device back to the
external device unchanged.
