5.2.2 ProLinx-S3964R Operation

The protocol realized on the S3964R has the following special features:

 Immediately after power-up and completion of the internal/external

initialization procedures the S3964R with installed 3964R protocol is ready to

serve as an interface between a controlling device and one or more

communication partners using 3964R protocol. The parameterization of the

module is realized through a configuration file. This is where a differentiation

between the communication modes 3964R with RK512 and 3964R without

RK512 takes place.

 The communication mode 3964R without RK512 supports processing of up to

512 bytes.

 The serial transmission parameters can be allocated independently to each

interface using the ProSoft Configuration Builder software.

5.3 Communications

5.3.1 Job Allocation by the Modbus TCP/IP Device

This section describes the different types of jobs and the relevant parameters to

be entered.

Every job that is transferred to or from the S3964R Communication Partner

consists of defined header data and user data. This data is stored in the module

database. The following data map shows how the data is mapped out in the local

database for each 3964R port.

Data Map Offset

0 299 Port 0 Receive

300 599 Port 0 Transmit

600 899 Port 1 Receive

900 1199 Port 1 Transmit

1200 1499 Port 2 Receive

1500 1799 Port 2 Transmit

1800 2099 Port 3 Receive

2100 2399 Port 3 Transmit

2400 2409 Port 0 Status

2410 2419 Port 1 Status

2420 2429 Port 2 Status

2430 2439 Port 3 Status

Message data received from the 3964R Communication Partner is stored in the

"Receive" section for each port.

Data that needs to be transmitted to the 3964R Communication Partner is stored

in the "Transmit" section.

The "Status" section contains the 3964R driver status for each port.
