5.10.4. TCP/IP Modbus
PCE-P30U transducers enable access to internal registers using the
Ethernet interface and TCP/IP Modbus Slave protocol. The functions
of Modbus protocol and structure of registers have been discussed
in section 5.9.3-5.9.6. It is required to set an unique IP address
for the transducer and to set connection parameters specified in table
45 to set up the connection.

The device address (
Ethernet
→
Adr mTCP
)
is the device address for TCP/IP Modbus protocol and does not
correspond to the address value for RS-485 Modbus protocol
(
Mbus 485
→
Adres
). If
Adr mTCP
transducer parameter is set
to “255”, the transducer will bypass the address analysis in the Modbus
protocol frame (broadcast mode).
