x328()

* = x328( [socket], par [, gid[, uid[, chan]]])
x328( [socket], par [, gid[, uid[, chan]]]) = value

Performs I/O with the Eurotherm temperature controllers, using the ANSI X3.28-2.5 A4 messages framing.

socket
A socket descriptor. The socket has been opened by a preceeding open/socket call. Socket may be omitted (but not the comma), if no /desc qualifer was supplied for the open/socket command.

par
Eurotherm parameter keywords, e.g.: PV

gid
Group id, optional

uid
Unit id, optional

chan

value
Value that is assigned to a parameter

e.g.:
open/socket/host=hast09/port=3538
x328(,SL) = 21
* = x328(,SL)
close/socket

The example demonstrates how the set point is changed and re-read.
