3.2.3

 

RTU master mode 

If the RTU master mode is active (this is a software option 
which must be purchased), the RTU-810 can operate as a 
master for a point-to-point to a point-to-four-point operation. 
 
This means, the RTU-810 can transfer any number of its 
internal digital and analog I/O to up to four other RTU-810's. 
 
The slave RTU-810 does not need to have also the RTU 
master option activated, this is only needed for the RTU-810 
which is the communication master to the slave RTU-810's. 
 
The RTU-810 will check the slave RTU-810's if they meet 
the configured requirements, i.e. if they provide at least 
enough digital and analog I/O as configured for exchange in 
the master RTU-810. If the requirements are not fulfilled, the 
concerned connection will change to an error state. 

 
In error state or when the radio link to a slave breaks, these actions will be performed: 
 

 

The digital and analog outputs on the master RTU-810 which are configured to 
the particular failed slave will be switched to OFF 

 

The digital and analog outputs of the respective slave are also written to "OFF" 
by the RTU-810 master 

 

If the radio link to the slave breaks, the slave will switch all its outputs to "OFF" 
if either the X-Timeout or the T-Timeout runs off (whatever happens first) 

 

The error will be displayed on the RTU master mode configuration page of the 
master RTU in the "ERROR messages" section 

 

The error will be written into the event logger of the RTU-810 

 
The RTU-810 will periodically check if the slave is available and fulfills the 
requirements for the connection. In that case it will (re)establish the radio 
communication immediately. 
 
The RTU-810 master will periodically exchange the configured I/O with the enabled 
slaves. The timeslot operation can be used to limit the transmission to a certain part of 
each minute, this fulfills the German requirements for time slot operation and can 
internationally be used to operate several systems on the same frequency within the 
same area. 
 
To fulfill duty cycle requirements a configurable pause can be inserted after each single 
polling and/or after each complete polling round.
