1. System Configuration
Data link mode
Two PLCs (any combination of T1S, T2E or T2N) can be directly linked together. This
direct link is inexpensive, easily configured and requires no special programming. Data
registers D0000 to D0031 are used for the data transfer.
Free ASCII mode
User defined ASCII messages can be transmitted and received through this port.
A terminal, printer, bar-code reader, or other serial ASCII device can be directly
connected. This mode also allows the T1S to communicate with other PLCs (T1, T2E,
T2N, etc.), Toshiba’s Inverters (such as VF-S7/A5, G3), Toshiba’s motor protection
relay (S2E21), or others.
