4.3 FMS Services

Before

you configure an FMS communication job, you must first define an

FMS connection using the COM5434 Configurator

. To establish a successful

connection, the services of the communication partners must be matched. As

requester

, you specify the services that you expect from the partner device.

As responder

, you specify the services you provide for the partner device.

NOTE:

The software generates an “Object Dictionary” that contains the

names and index numbers of the FMS variables you configure. To enable

partners to access variables by name, enable the Get Object Dictionary

service when configuring an FMS connection. (Refer to Figure 5-15.)

o define an FMS connection using the COM5434 Configurator

, follow the

steps described in Section 5.6.

The FMS CP module acts as a client (initiator) for the following FMS jobs:

•

Read – reads data from a data area of the communication partner

specified by a name or index.

• W

rite – transfers data from a specified local data area to a data area of

the communication partner

•

Information Report – allows unconfirmed transmission of variables by

an FMS server

•

Status – the partner device sends logical and physical status

information that may include the following items: whether

communication is possible, for example, CPU is in RUN; physical

status of CPU, for example, maintenance is required. (Refer to

Section A.3 for more information about Status request responses.)

•

Identify – the partner device sends three ASCII strings that provide

the following information: name of the device vendor

, name of the

device model, and revision or version of the device. (Refer to Section A.3

for more information about Identify request responses.)

The FMS job types are described and illustrated in Figure 4-4.

These coordinated client jobs must be configured in the client module. T

configure an FMS job, follow the steps described in Section 5.9.

The server station must also be configured to coordinate with the client

station. Y

ou must configure coordinating FMS connections for all FMS job

types, and FMS variables for Read and W

rite jobs in the server station.
