box"). In this case, you can also configure in such a way that the first slot has

no device allocated to it and the size of the first slot corresponds to the mail-

box size. This does mean, however, that one less device can be linked, but the

up-to-dateness of the process data is not dependent on the masking or unmask-

ing of the mailbox. But this is only possible for the module configured as the

master since slave process images always consist of only one individual slot

(in the master) and these do not begin until the third byte.

After configuring the process image and mailbox size, you can continue with

the device configuration. Please make sure that the module is in configuration

mode for the remainder of the steps.

Assign each device its intended role (master or slave). For each slave, enter

the master in the first slot in the list of allowed WAGO devices. For the mas-

ter, all intended slaves are assigned slots in the list of allowed WAGO or ex-

ternal devices. For each slot, set the planned data width (cutoff).

For master/slave communication over Bluetooth

, make sure that the settings

for encryption, authentication and PIN are identical in the devices. For maxi-

mum security, it is recommended that you keep the factory setting for "En-

cryption" at "On" and "Authentication" at "Password". The preset password,

“0000” should be changed to a project-specific password.

At the end of the device configuration process, you will change to communi-

cation mode - in the ad hoc or real-time profile, depending on the type of

slaves. With correct configuration, devices within range should automatically

establish a connection to each other. The establishment of a connection is es-

pecially fast if you first startup the slaves and then the master.

As soon as the connections are established, master and slaves exchange data

with each other, depending on the slot configuration. You can continue to set

mailbox commands in communication mode as well. An example being to

change the operating mode again or to query diagnostic information.
