End User Interface Module

End User I/O Module

The End User I/O Module is an off-the-shelf I/O module providing streamlined access to user connections on the high-density connectors on the LEC-1 embedded scan control board.

The End-User I/O Module presents connectors for interfacing to external devices such as lasers, automation equipment, and factory networks. The LEC-1 provides very flexible System I/O control capability for applications that require the LEC-1 to interact with other process control equipment. Not all signals may be required for a given process control scenario. There are four fixed purpose system outputs and 5 fixed purpose system inputs. An integrator need only select an appropriate subset of these signals.

The End-User I/O Module has been designed to interconnect directly with the LEC-1 using standard ribbon cable assemblies included with the module, and provides most of the signals available on the LEC-1.

System Outputs

  • Error / System Enabled. From a cold start, or a reset, this output will stay low until the LEC-1 has completed it’s initialization routines and is ready for operation. After start-up, this output will go low if the following occurs: software exception, interlock trigger, or opcode command exception.
  • Job Busy. This output indicates when a job is busy marking. Job Busy goes HIGH when the first object starts marking, and stays HIGH until the last object is finished marking. Job Busy then goes LOW.
  • Ready. This output indicates when the LEC-1 is waiting for a Start Mark signal. Normally in the LOW state, Ready will only switch HIGH when the LEC-1 is waiting for a Start Mark signal. When the Start Mark signal is received, Ready switches to LOW. The Ready output will not change state if a job is executed from the software with the External Start feature disabled.
  • Mark In Progress. This output indicates when an individual object within a job is executing. Mark In Progress will switch HIGH when an object starts marking, and then switch to LOW when the object completes its marking.

System Inputs

  • Start Mark. This input is used to start the job marking sequence. The marking job must be configured to use the External Start feature. To start the marking sequence, switch the Start Mark input to HIGH.
  • Interlock 1-4. Four individual Interlock inputs are provided as a means to immediately abort the current process and set all outputs to the Idle (LOW) state. To signal an Interlock input, switch the input to HIGH.
