Entering a Device in the Table of Allowed Devices

AllowRemoteDevice, 0x83
This command is used to allow a remote 750-644 I/O module or Bluetooth
device access to the local 750-644 I/O module. The MAC ID of the remote device
is also entered in a table of the Bluetooth
differentiated. Both types are entered in different tables:
• 750-644 I/O modules for "Real-Time Communication" mode:
WAGO_DEVICE (0x20 ... 0x26)
• Bluetooth
EXTERNAL_DEVICE (0x10 ... 0x15)
Access permission
Before an entered 750-644 I/O module is actually authorized access, it must be
enabled using the command "BindRemoteDevice".
Access permission can be revoked using the command "UnbindRemoteDevice"
without requiring deletion of the device from the table.
• Entries can be deleted from the table by overwriting with the MAC ID
00:00:00:00:00:00. The respective slot is populated with 0. No data is
transmitted to it.
• Changes to the device blocks do not change anything in the process
image mapping.
• A MAC ID (exception: MAC ID 00:00:00:00:00:00) may never occur
more than once in a table.
