GlueLogix Timing Control Unit (TCU)

The core of most GlueLogix designs is the Timing Control Unit (TCU).  Designed around an 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

Common Features:
  • Parallax Propeller, 5 MHz External Clock (software sets 80 MHz internal clock)
  • Reliable control loops down to 100 uS
  • input response less than 1 uS
  • 9-24VDC capable
TCU V3:
  • 6 industrial I/O interfaced through Grayhill Standard modules. I/O configuration is changeable by plugging different modules. 
  • 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.
  • 3 dedicated stack light outputs (RED, YELLOW, GREEN).
TCU V4:
  • 18 I/O interfaced through socketed LTV series optoisolators.
  • I/O direction is solder configurable.
  • Standard I/O configuration is:
    • First 6 I/O match standard TCU V3 configuration
    • Next 6 are outputs
    • Last 6 are inputs.
  • 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.
  • 9-24 VDC, reversible, on standard  2.1mm jack.
  • Through Holes for additional +- power supplies.
  • 3 dedicated stack light outputs (RED, YELLOW, GREEN).
  • Isolated USB connection
  • 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, the TCU could drive up to 12 UARTS.

Status Sep2016

  • TCU V4 used in one project, as a high speed controller for Voyantic Tagsurance.  Available with lead time as finished board and as a source licensed design.
  • 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.
  • Ladder Logic software in long term development.
