LINK TechBox/TechCard Instruction Manual - HA470016 Issue 5
Appendix A-Using Tag Readers and Tag Writers
With the drive configured to accept the
LINK
Technology Option, the interface between the
Techbox/Techcard, the drive and the
LINK
system needs to be programmed for the specific drive
and application. The Techbox/Techcard can be perceived as a
LINK
processor, which treats the host
drive as an I/O device. Drive parameters are accessed by tag numbers which are unique to each
parameter and can be found under “Specification Table – Tag Number Order” in the drive
instruction manual.
Function Blocks
ConfigEd has two types of function blocks for the
LINK
Techbox/TechCard:
Tag Reader block that reads a drive parameter; the Tag Writer block that writes to a drive
parameter.
Each of these blocks can be subdivided into two classes, Ordinal and Value. Ordinal Readers
and Writers handle integer or logic data and cannot be scaled. Value Readers and Writers
handle continuous variables and have special scaling assigned to them. Scaling choices are
representative of standard ranges found in a drive and include choices of 100%, 120%, 150%
and 200%, each representing a full scale “1” within
LINK
.
You will need ConfigEd (version 5.13), or DSD with database properties of platform rev. 14-0,
library rev. 115-0, instruction rev. 9-0 and class rev. 604-0, and all subsequent revisions, to
build a configuration for the
LINK
techbox. For details on how to use this package, refer to the
ConfigEd instruction manual RG353792.
Additional
LINK
function blocks may be inserted into the Techbox/Techcard configuration.
The Techbox/Techcard has approximately 2/3 of the memory capability of the L5300. In terms
of storage units the Techbox/Techcard has 4 units. A Section Control block requires 1 unit of
storage, SPW 3 winder block requires 2 units of storage.

WARNING
LINK configurations should be created by qualified personnel who have a
thorough understanding of drive systems and who are LINK trained by Parker
SSD Drives. Potentially dangerous configurations are possible and Parker SSD
Drives is not responsible for any resulting consequences or damages.
•
In ConfigEd, open up the project in which this techbox will appear.
•
From the
File/New
menu, pick
LTechBx2
, the default template for a LINK techbox/techcard.
This template contains an AUTO-TAG LOADER. The AUTO-TAG-LOADER will
automatically access and load parameters into the drive during the power up sequence. (The
L
TechBox
template contains a MANUAL-TAG-LOADER function block. The parameters in
the tag readers and writers are manually triggered.)
•
When prompted, furnish the node address and name for the techbox.
•
Two blocks should be visible on a blank page, named
TB
I
and
System.
