2.5 Module RTU

The S4 module provides a RS-485 communications module for Series 

S of panel meters. ASCII protocol with ‘Master’ / ‘Slave’ architecture. 

Addressable with up to 31 modules. Frames codified in represent

-

able ASCII characters (codes 32 to 255), directly visible using ‘hyper

-

terminal’ or similar programs.

•  Configurable  for  direct  retransmission  to  remote  meters  M60-

485 (14 mm digit height) and BDF Series (60 mm and 100 mm digit 

height).
• Access to display values, alarm status, memory of maximum and 

minimum, alarm setpoints, ...
Configuration from instrument front keypad, through menu entries 

‘Opt.1’ or ‘Opt.2’, depending on the position the module is installed.
The S4 module can be ordered pre-installed into a Series S panel me

‘Opt.1’, ‘Opt.2’

The RTU module provides a Modbus RTU communications module 

for Series S of panel meters. The RTU module implements function 

‘4’ (‘Read Input Registers’) of the Modbus RTU protocol, to access the 

instrument registers (reading value, alarm status, memory of maxi

mum and minimum, ...)
Configuration from instrument front keypad, through menu entries 

‘Opt.1’ or ‘Opt.2’, depending on the position the module is installed.
The RTU module can be ordered pre-installed into a Series S panel 

meter, or standalone for delayed installation, as it does not require 

soldering or special configuration.
