5.4 Serial Communication with a Host Controller

The control module communicates with a host process controller via RS-232 or

RS-485 protocol and at the baud rate specified in the Serial Communications box

(section 5.3.1). The System provides a number of data transmission options.

5.4.1 Serial Data Transmission

The serial transmission portion of the PSF Configuration screen activates the serial

port(s), specifies the data format, and provides data suppression options. These

settings are required to allow a control module to communicate with a host computer

or process controller. If No Serial Communication is selected (the default setting),

the serial port(s) will not transmit sensing data.

Measurement Mode Result: data transmitted will be the values output for the Scan

Analysis Mode selections. Up to two Scan Analysis Mode selections can be active.

ALL Mode: the status of each beam in the light screen array will be transmitted for

each scan. In ALL mode, blanked channels are transmitted as unblocked (or clear)

beams.

Max Meas Mode: the control module records the maximum measurement value

registered while the light screen is blocked. That data may be transmitted to the host

either when the array is clear at the end of the sensing event (select Send On Clear),

or when prompted by the host (select Send On Request). This mode reduces the

amount of serial data sent.

5.4.2 Transmission Type

Transmission type defines the format in which data is sent. The ASCII option causes

the control module to send data in three ASCII-coded bytes. The Binary option causes

data to be sent in binary format, reducing the amount of data per measurement mode

from three bytes to two. For more information on the data formats, refer to Appendix

A.
