Asynchronous serial link module
The 140 ESI
communication module that can be used to exchange data messages with third-
party devices.
This module is particularly suitable for use in applications with printers, bar code
readers and scanners, or devices communicating via a serial link, such as weigh
scales, meters or other measuring devices.
This module has been designed for relatively simple point-to-point ASCII
communications. A resident command interpreter can be used primarily to specify
the formats and baud rate of the communication ports in operational mode, using a
serial link management utility such as Microsoft
also be used to enter ASCII message formats that will be stored in this module.
These message formats constitute the base for organizing communications. For
example, using an appropriate syntax, these formats define for transmissions, the
fixed characters that must be sent on the communication line. These transmission
message formats can also be used to specify the sending of data that is an image of
the card registers, in accordance with a particular representation (binary, integer,
ASCII, etc.).
For reception, the message formats used are usually limited to specifying a wait for
a certain number of values or characters, directed to the module's internal data
registers. Unlike transmission, the specifiers used on these reception message
formats can be used to define the numerical base(s).
The Quantum PLC application program communicates with the asynchronous serial
link module via mailbox registers. These registers submit commands to the module
and translate the responses. Communication commands are processed by
requesting transmission on a port, through the use of a message format. Conversely,
it is possible to listen for reception on this port, through the use of a message format.
If the exchange mailboxes between the PLC and the module are not large enough to
carry the application data required for a transaction, at the same time as the
transmission and reception commands, additional commands (Get/Put) will be used
for exchanges between the PLC database and the module's internal registers.
Note: In LL984 programming, with Concept and ProWORX programming software, it is possible
to use an additional instruction (ESI
exchange sequences between the PLC application and the asynchronous serial link module.
This programming software also requires integration of special software (NSUP and ESI
PLC configuration (Concept IEC uses only ESI
diskette, supplied together with the asynchronous serial link module hardware reference guide.
