CEN-OEM-Specific Definitions
CEN-OEM Specific Definitions Overview
The CEN-OEM has one serial port which is used to communicate with a destination
device. SIMPL+ defines several special purpose variables exclusively to work with
the CEN-OEM to manipulate this serial port. These variables are only valid when the
file is saved with an OEM extension. Each OEM variable has a specific type
(DIGITAL_INPUT, etc.) to which all the same rules as any other variable declared
of that type have.
In the following examples, the “device” port is the port that talks to the equipment
(device) being controlled. The “main” port is the computer port of the CEN-OEM.
This port is usually used for communicating with a host computer for maintenance,
but various pins may be used for other applications as shown in the following
examples.
_OEM_BREAK
Name:
_OEM_BREAK
Syntax:
_OEM_BREAK = <expression>; // Write to Variable
or any expression that can use a variable as part of its contents.
Description:
When set to a non-zero value, causes a short break to be transmitted on the port. A
Short break is 17-20 bits of logic low. When the system is done generating the short
break, it will set the variable to 0. The variable may also be read back from to
determine its current status. It is treated the same as a DIGITAL_OUTPUT.
Example:
_OEM_BREAK = 1; // Generate A Short Break
