1.16 Registers in ‘Process slave’ mode
List of registers accessible (see Table 3) for an instrument configured
in ‘Process slave’ mode.
• register 0 contains the value to show on display. It is a numerical
value, with or without polarity at the first character (‘+’ or ‘-’) and
with a single decimal point, or without decimal point.
Example 1 : send characters ‘+’ ‘7’ ‘4’ ‘.’ ‘6’ ‘1’ to read on dis -
play ‘74.61’
Example 2 : send characters ‘-’ ‘0’ ‘4’ ‘6’ to read on display
‘-46’
• registers 3, 4 and 5 contain the setpoint values for alarms 1, 2
and 3. By default, write access to these registers is disabled (set -

• write frames to the setpoint registers when they are dis-
abled will return error 8 ‘Read only register’.
• to save into the E2PROM the values written through the bus
into these registers, (values will be maintained incase of pow -
er loss) enable parameter ‘E2Pr’
(see section 1.28.10)
.
• after power loss, the instrument will start-up with all registers
initialized to a value of ‘0’
