*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 designate 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 command number (0000H) is the same as the "Data Read".
∙A transfer size error (TermSTS = 09H) occurs if the transferred register data length exceeds the range 1 to 128 words (or 1 to 83 words for the T and C registers).
∙A register designation error (TermSTS = 01H) occurs if a value other than a stipulated value is designated for the register type codes (Register type
∙A register designation error (TermSTS = 01H) occurs if 0007H (the T register) is designated for the local station register type code and a register other than T register is designated for the remote station 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 designated for the T register.
∙For data storage registers, a boundary error occurs if the designated area (leading address + register range) does not exist in either the local or remote stations.
