Bank number ... 00H: T3H internal registers
F0000 to F32767
01H: Expansion F registers (IC card) F0000 to F65535
02H: Expansion F registers (IC card) F0000 to F57343
*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.
