PowerMACS PLC with PLUS_CHECKCOM, failed.
Outputs seen from the PLC:
Variable Type Use
PLUS_CHECKCOM BOOL On
a positive edge a test telegram “TSTS” is sent to the PLUS
server.
PLUS_BUSY will be set to TRUE and PLUS_CHECKCOM_OK
and NOK will be set to FALSE. Then the test has finished
PLUS_BUSY will be FALSE and PLUS_CHECKCOM_OK or
NOK will be TRUE, depending on the result of the test.
Has the same functionality as the Test button in ToolsTalk
PowerMACS.
PLUS_GETTMU BOOL
On a positive edge the value in “PLUS_BARCODE” is sent to
PLUS in a request for a TMU and a PN or KN.
PLUS_BUSY will be TRUE during the transfer and
PLUS_GETTMU_OK will be TRUE when the result is ready for
usage.
The result of the request will be placed in CURRIDSTRING (the
PN or KN) and PLUS_MODE (mode number from conversion of
received TMU). CURRIDSTRING will have the letters „PN‟ or
„KN‟ added as a prefix to the string received from PLUS.
If “Station Type” in the PLUS device is different from SAW/WIS
nothing is sent to PLUS. Instead the string in PLUS_BARCODE
is copied directly to CURRIDSTRING with the letters „PN‟ or
„KN‟ added as prefix. The string in PLUS_OVERRIDETMU will
be sent to the conversion table to get PLUS_MODE.
In a VBA station nothing at all will happen when a positive edge
is sent to PLUS_GETTMU.
PLUS_BARCODE STRING
(10) Id string that is sent to PLUS to get a TMU and PN or KN. If the
string is treated as a production number “PN”, a body number
“KN” or a carrier Id “LI” is controlled by the parameter “Barcode
scanned” in the PLUS device in ToolsTalk PowerMACS.
PLUS_BARCODE is sent on a positive edge on
PLUS_GETTMU and the result can be used when
PLUS_GETTMU_OK is set to TRUE.
The returned PN or KN will be copied to CURRIDSTRING with
the letters PN or KN added in the beginning. This string will be
included in the cycle data as "Wp ID". The TMU received from
PLUS will be converted to a mode number using the conversion
table in the PLUS device. The result will be placed in
PLUS_MODE.
