Buffer memory list

The table below provides a brief description and reference information for the 64CCL buffer memory.
BFM No.
FROM instruction: remote outputs (RY)
#0 to #7
TO instruction: remote inputs (RX)
FROM instruction: remote registers (RWw)
#8 to #23
TO instruction: remote registers (RWr)
#24 Transmission rate, hardware test set value
#25 Communication status

#36 Unit status
#37 to #59 Not available
#60 to #63 Consistency control
The 224 remote inputs (RX000 to RX0DF)
#64 to #77 These devices set the ON/OFF data to be sent to the master station when the TO
instruction (or direct buffer memory specification) is executed.
#78 to #119 Not available
The 224 remote outputs (RY000 to RY0DF)
#120 to #133 These devices read the ON/OFF data received from the master station when the
FROM instruction (or direct buffer memory specification) is executed.
#134 to #175 Not available
32 words (RWw00 to RWw1F) of remote registers
#176 to #207 These devices set the word data to be sent to the master station when the TO
instruction (or direct buffer memory specification) is executed.
#208 to #303 Not available
32 words (RWr00 to RWr1F) of remote registers
#304 to #335 These devices read the word data received from the master station when the FROM
instruction (or direct buffer memory specification) is executed.
#336 to #511 Not available
Link special relay SB
#512 to #543 The operator can check the data link status using the bit information of these
devices.
#544 to #767 Not available
Link special register SW
#768 to #1279 The operator can check the data link status using the word information of these
devices.
#1280- Not available
R/W : Read/write is possible
R : Read only
*1. Read/write is only possible when the expanded cyclic transmission is set to "single."
*2. When writing to an area without assigned link points, writing is invalid. When reading from an area
without assigned link points, the reading operation results in "0" being read.
*3. Only a value of "0" can be written and accepted.
