LDIB via the Allen–Bradley MAP Station Manager. Refer to the MAP
Station Manager User’s Manual for more information (publication
6630–6.5.2).
The OPEN command has the following syntax:
OPEN <connection> TO <application entity name>
The following table defines each part of the OPEN command line.
This: is:
OPEN the command that initiates the connection. You can abbreviate to one
character, upper or lower case. Leave at least one space between each field
in the command line.
<connection> the communication link established between two points. You label
connections using the connection symbol :C followed by an integer from 1 to
9999 (you do not have to use them in any particular order).
TO a qualifier. You can abbreviate as T and use upper or lower case letters.
<application
entity name>
the application entity (AE) name of the remote node with which you are
establishing a connection. You must match the AE name to an entry in the
OSI coprocessor LDIB. The AE name must start with either single or double
quotes (and up to 64 characters long). You set up AE names via the A-B
MAP Station Manager (see the station manager's user manual, publication
6630-6.5.2, for details).
For example:
open :C8 to ’paint_booth_54’
the command
the connection identifier
followed by the number 8
a qualifier the AE name paint_booth_54 is associated with an
entry in the LDIB.
Here are more examples of using the OPEN command:
OPEN :C16 TO ’STATION_33’
OP :C999 t ’wheel_10’
Terminating Connections With Other Nodes (CLOSE and ABORT)
The CLOSE command gracefully terminates the connection with a
remote node on your MAP network. You can close only the connections
you established from your local PLC–5 controller (figure 4.6).
