Getting Started

Many operator interfaces can be used as

a network master station to

communicate with one or more slave

stations. An operator interface must

have a driver that supports the

DirectNET protocol.

Make sure your operator interface uses

one of the following protocols or has a

driver for the equipment listed.

S DirectNET (DL430, DL440,

D4–DCM)

S Hostlink (TIt or Simaticr TI425,

-430, -435, U-01DM)

S CCM2 (GEr Series Onet)

Many companies advertise some of their

operator interface products will operate

with the DirectLOGIC family of

products. Check with your operator

interface supplier to see if they offer

versions for use with the DirectLOGIC

products.

Operator Interface

Many applications utilize a computer to

act as a central data collection point and

to manage the network requests for data

transfer. The advantage with this

approach is you can perform many

different types of operations with the data

either before or after a request.

The disadvantage is you may have to

write your own communications driver

and that can take a considerable amount

of time for more complex applications.

The communications programming is

difficult unless you have a considerable

amount of network programming

experience. The programs must utilize

the DirectNET protocol used by

DirectNET.
