14. Remote Tags
14.1. Introduction
Remote Tags allow exchanging information between two or more ModBus stations via any
communication ports.
Typically, it is a
TB
OX
MS
connected to another
TB
OX
MS
, either local (through RS485 or
Ethernet) or remote, by modem.
One often speaks of 'Master Network' because it is a Master/Slave communication: the
Master executes reading and writing in slave(s).
TB
OX
MS
, being ‘Master’, reads and writes the variables with all other devices using the
ModBus protocols (ModBus-RTU or ModBus/TCP, according to the kind of communication)
Each Remote Tag corresponds to one transaction (reading or writing) with 1 slave.
When there are several stations,
TB
OX
MS
executes the different transactions of one station
at a time, then transactions of the following station, and so on …
Any communication port can be used to execute Remote Tags: RS232, RS485, modem
PSTN, modem GSM, Ethernet.
When a modem port is used to execute Remote Tags,
TB
OX
MS
needs first to establish the
connection using an Alarm of type ‘ModBus’ (see chapter 12.4.
