The core of most GlueLogix designs is the Timing
Control Unit (TCU). Designed around the Parallax Propeller 8 core by 32
bit RISC processor, the TCU can be configured for a wide
range of input and output configurations.
Two versions of the TCU are currently active.
Version 3, introduced in 2010, is in use in around 50
applications. Version 4 is used for
EncodeInMotion
and other high end applications. Version 4P2, based on the Parallax Propeller2 with double the memory and triple the speed of P1, is in development with release planned in 2023.
Reliable control loops down to 100 uS (unlike any PLC)
input response less than 1 uS (unlike any PLC)
9-24VDC power input
TCU V3:
6 industrial I/O interfaced through Grayhill
Standard modules. I/O configuration is
changeable by plugging different modules. Options are 60 VDC and 110 VAC.
Standard I/O configuration is 1 DC input (GAP), 5
DC output (STOP, MARK, ERR, BAD, GOOD)
4 RS232 serial ports, one with DTR (PC) others
3-wire (RFID readers). Up to 7 serial ports can
be set up with wire changes using onboard level
shifters.
Last 6 are inputs.
This board is optimized for 24VDC I/O.
5 RS232 serial ports, one with DTR (PC), others
3-wire (RFID readers). Up to 11 serial ports can
be configured in software with external level
shifters.
Not formally tested yet, but does not reboot when
hit with piezo spark source
The Parallax Propeller chip itself uses soft
peripherals, so with proper I/O conditioning, TCUv4
could drive up to 12 UARTS. TCUv5 has 12 UARTS, 18 I/O, Ethernet and USB.
Status Mar2023
TCUv4P2 first boards made, software in progress.
TCUv4 available as finished board or source licensed design.
Multiple TCUv4 used to implement first delivered EncodeInMotion system.
TCUv4 in use as multilane RFID read controller in on-press test systems designed for Tamarack Products.
TCU V4 used as a high speed controller for Voyantic Tagsurance, before they had their own I/O box.
TCU V3 used in around 50 projects.
Available as finished board and as a source licensed
design.
IndustRFID firmware reads HF and UHF at 20/sec
using Feig readers, and ThingMagic Vega
historically. It also encodes and controls the
stepper in the GlueLogix
rewind machine.
