Ecco tutto quello che c'è da sapere
The PLC BASIC Module (1771-DB) occupies one slot in the 1771 I/O chassis and runs user-written BASIC and C programs. These programs are independent of the PLC processor and provide an easy, fast interface between a PLC processor, 1771 backplane and RS-232, -422, or -485 devices. The BASIC module can also communicate with a remote SLC processor or remote device on the DH-485 network through a DH-485 port.
The AB 1771-DB PLC BASIC Module allows for:
