RS-232C to RS-485 Conversion (continued)
Ethernet Connection using GS-EDRV(100)
The GS-EDRV(100) provides a high-performance Ethernet link between a control
system and a DURA
PULSE AC DRIVE. It mounts on DIN rail and connects a drive to
an Ethernet hub/switch or PC. The GS-EDRV(100) processes signals to and from
the drive. It formats the signals to conform with the Ethernet standard to the
H2-ERM(100) or H4-ERM(100), KEPdirect EBC I/O server, or independent
controller with a MODBUS TCP/IP driver. This Ethernet interface allows for great
connectivity to many control system architectures. An additional feature is the
built-in web browser which allows users to configure and control the drive from
any web browser via the IP address of the GS-EDRV(100) card.
A cable that will connect the DL450 to the FA-ISOCON can be constructed using the
DB25-pin-male-to-RJ12 adapter and the RJ12-6P6C cable from the FA-CABKIT.
