TermSTS

Detailed information (Only valid when TermSTS = 0BH.)

(d)Important items

∙The command number (0000H) is the same as the "Data Write".

∙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 (self/target-station)).

∙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.

Local station : TermSTS = 0AH ; Remote station : TermSTS = 8AH

∙A response time-out error (TermSTS = 02H) occurs if the response time from the remote station exceeds the time designated by the response time limit.
