*2 Includes the expansion F registers(Only T3H). One bank has 64K words (0 to 65535).
F 7 0
06
*3 The T and C registers hold data that has flags attached.
Supplement:
The transfer data length has a maximum of 323 words when data is transferred over the
Ethernet.
For the T registers, it is not possible to specify a range that spans both the basic T
registers (0 to 511) and the expansion T registers (512 to 999). The T3H has the expansion
T register, but the T2N does not have.

d. Important items
• The write operation is not synchronized with the remote port T2N/T3H scan operation.
If synchronization is necessary, applications must perform synchronization processing, such as
transferring the data to a separate registers at the start of the T2N scan.
• The command number (0021H) is the same as the "Data Read".
• A transfer word count error (TermSTS = 09H) occurs if the transferred register data length
exceeds the range 1 to 485 words (or 1 to 323 words for the T and C registers).
• A register specification error (TermSTS = 01H) occurs if a value other than a stipulated value
is specified for the register type codes (SRID/DRID).
• A register specification error (TermSTS = 01H) occurs if 0007H (the T register) is specified
for the local port register type code and a register other than the T register is specified for the
remote port register type code. This also holds for the C register.
• A boundary error (TermSTS = 0AH) occurs if a range spanning both the base T registers (0 to
511) and the expansion T registers (512 to 999) is specified for the T register.
• For data storage registers, a boundary error occurs if the specified area (start register + register
range) does not exist in either the local or remote ports.
Local port: TermSTS = 0AH, remote port: TermSTS = 8AH
• A response timeout error (TermSTS = 02H) occurs if the response time from the remote port
exceeds the time specified by the timer counter value.
