Data Highway Plus (DH+) / Remote I/O (RI/O) Adapter
STD32 BUS Interface Card

The DH+ / RI/O Adapter Card is a STD32 based module which allows STD32 bus computers or OEM based applications access to AB's DH+ and RI/O networks. The Interface Card allows exisiting 1770-KF2, and PLC CH0 Serial DF1 drivers to run at STD32 bus speeds. This will allow MMI, HMI, SCADA equipment, and other computer applications access to any DH+ node including PLC's and SLC's.
All settings are accomplished using an easy to use Windows based Configuration Program over the bus or by using an external RS-232 connection to another computer.
