12. Configure Expansions
This lateral 2.5 mm jack socket serves to expand the product with various accessories. There are some items to be observed:
• Whether and which accessories are offered for the product can only be found out via the website for the product at www.conrad.com in the
accessories list. Only accessories listed here must be used with the product.
• After purchasing accessories, a firmware update may be required to support the new functions. The firmware version as of which the accessories
are supported are stated in the operating instructions for the accessories.
• All commands, parameters, functions and function changes can be taken from the operating instructions of the accessories.
• There are further requirements in the operating instructions.
• You may find a new version of the operating instructions available to you in the download area.
A general description of the planned configuration command is:
SET EXTERN <short name of the product> <Parameter> … #1513
<Short name> means the name of the accessory or its function. This selects the communications protocol to be saved with this accessory. The
following parameters serve configuration of the accessories and are forwarded.
There is the option of expanding various other commands by another setting when using external accessories. This information is also included
in the operating instructions for the accessories.
Generally, the following rule applies:
The following command is always able to determine the current confirmation of this expansion interface:
TEST EXTERN #1513
Deactivation and general resetting of the function and product:
RESET EXTERN #1513
Example: A switching input can be developed as accessory for which the input pins are visually separated and that therefore can also be used
in the industrial area. The product may have the internal name “OPTO” for optocoupler (technical name of the component). This product might
be configured as follows:
SET EXTERN OPTO <Reaction at> [<TIME>] #1513
Reaction at: LH = when switching on,
HL = when switching off,
LHL = at every change
OFF = same as RESET, switches off function
TIME: Time in seconds, 1......90 seconds
The first parameter defines the flank (condition change) at which an alarm is to be triggered. For the optional 2nd parameter, the time is entered
for which the input may remain in the “forbidden” condition before an alarm is to be triggered. For example, short impulses may be ignored.
Examples:
Alarm report when changing from LOW=L to HIGH=H
SET EXTERN OPTO LH #1513
Alarm report when changing from HIGH=H to LOW=L
SET EXTERN OPTO HL #1513
Alarm report at any level change:
SET EXTERN OPTO LHL #1513
Deactivate alarm via IN1:
SET EXTERN OPTO OFF #1513
Reset to factory settings (OFF):
RESET EXTERN #1513
