5.2.2 ProLinx-S3964R Operation
The protocol realized on the S3964R has the following special features:
ƒ
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.
ƒ
The communication mode 3964R without RK512 supports processing of up to
512 bytes.
ƒ
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.
