915U-2 Wireless I/O

E.g. Write to Register 1 with a count of 8 and a value of 1 will turn all the Local Digital Outputs
on.
Write to Register 40001 with a count of 2 and a value of 49152 will turn all the Local Analog
Outputs to 20mA.
Note: If when reading a register and getting the symbol “~“this indicates that the register has
not been written to and so it has no value (not even zero).
Note: if there is a mapping configured and any one of the source register values has
an invalidated state “~“ the mapping will not be sent (see 3.1 “Fail Safe
Configuration” below for more details.
A mapping will only be sent when all registers have a value. You can use the Fail Safe Block
Configuration to set an initial value for registers on start-up. This can be done using the
Configuration software or Web based configuration. See Configuration Supplements for details.
Using the I/O Diagnostics you can check the register locations for these “~“ values and even
write values if required.
If when reading the Status of the DIO on the module you see the value “3”, this indicates that
the DIO is being used as an output in the “ON” state.
3.9 Statistics
The Statistics webpage is used for advanced debugging of 915U-2. This webpage details the
state of the 915U-2 and performance information.
The page is useful to ELPRO technical support personnel in diagnosing problems with the
module.
Note that when updating the Statistics webpage, it is necessary to hold down the <ctrl> key
while pressing the refresh button. Otherwise, the information will not be updated.
