Mappings configure when to send specific information to another module and how the data is

sent. You can send input data:

 When the input values change (also called “Event reporting”); or

 Event reporting and on a timed basis (also called “Timed Update”).

Mappings cause the WI-I/O 9-L-T to transmit messages when any of the inputs used by the

mapping change state. You can also configure your unit to send messages if there are no

state changes for a while.

Feature Description

Mapping

name

Optional user-defined name for the mapping.

NOTE: WI Series only stores the mapping name in the configuration file; the mapping name is not

transferred to the module during configuration. This means that loading a module will not reproduce

any user-defined names assigned to the mappings.

Transmit

count

Number of times to transmit the same message. For example, if you set Transmit count to 1, the WI-

I/O 9-L-T transmits the message once, if you set the value to 2, the WI-I/O 9-L-T transmits the

message twice, etc.

Setting the transmit count to a higher number (up to 8) helps the message arrive at its intended

destination if the radio path is “marginal”. For large systems, excessive transmissions may cause

slow response. Weidmuller, Inc. recommends setting a transmit count of 2 or 3 for good radio paths,

and 4 or 5 for poor radio paths.

Delay

Before Tx

Number of seconds to wait after the mapping is triggered before transmitting the message. For

example, if you set Delay Before Tx to 5.0, the WI-I/O 9-L-T waits 5 seconds before transmitting the

message.

Setting a longer Delay Before Tx (up to 127 seconds) helps synchronise closely spaced changes to

different inputs sent in a single message. Once the mapping is triggered, the WI-I/O 9-L-T

incorporates any changes to the state of inputs during the Delay Before Tx period in the message

that is sent.

Update

Time

If a “change” trigger does occur not in the Update Time, the WI-I/O 9-L-T triggers the mapping and

transmits the message. This is known as an “Update message”.

Whenever the mapping is triggered (by either a change or an update), the WI-I/O 9-L-T restarts the

timer.

For example, if you set Update Time to 0:2:30:00, the WI-I/O 9-L-T sends the message 2.5 hours

after the last time it was sent unless a change of state causes the mapping to be triggered before this

time elapses.

Paralysis

Time

Minimum number of seconds to delay after sending a message before the mapping is re-sent. For

example, if you set Paralysis Time to 300 seconds, the WI-I/O 9-L-T will not transmit a message for

300 seconds after sending the last message sent. If the mapping is triggered during this time, the WI-

I/O 9-L-T delays transmitting the message until the Paralysis Time has passed. This forces a limit on

the number of transmissions that can occur.

Disable Lets you enable/disable the Update Timer and the Paralysis Timer.
