Eurotherm Group Standard Parameters
Each of the Eurotherm Group instruments which support ASCII protocol contains a minimum set of parameters. These are
known as the Prime Set and allow access to the following:
Mnemonic Description Access Function
BL Buffer length R/O Returns 4646
16
indicating that both transmit and
receive buffers are 46
16
bytes long.
CI Configuration
Information
R/O Returns 4CCC
16
indicating that the drive supports
both fixed and variable length data formats, and
that the drive is a single-function device.
EE Error report R/W Returns one of the following to indicate the status
of serial link transmissions :
00C0 No errors
01C7 Unknown mnemonic
02C2 Block check character fail
03C1 Parity error on received data
03C2 Framing or overrun error
05C8 Attempt to write to a read-only mnemonic
07C7 Invalid message format
08C8 Value in selection message out of range
Writing any value to mnemonic EE resets it
to 00C0.
II Instrument R/W Returns the value of a parameter, the default value
of which is 5840
16
.
MN Mode Number R/O Returns a fixed value 08C1 (the full Eurotherm
standard is not supported).
VO Version Number R/O Returns the issue number in the upper two
characters, and the release number in the lower
two characters. For example issue 2.1 returns
0201.
In addition to the Prime Set, each drive or instrument supports an application set of parameters to allow fast access to
commonly required variables such as:
a. Process variables.
b. Setpoints.
c. PI gains.
All parameters can be found by polling the instrument identifier parameter and then sequentially polling until the instrument
identifier parameter is repeated. This will result in a circular list that contains all supported by the instrument.
