Network Configuration Data Frames; Keep Alive Frame - ADEUNIS WMBUS DRY CONTACTS Guide Utilisateur

WMBUS DRY CONTACTS - Guide utilisateur / User guide version V2.0.0
• Byte 6=0xB4: register 322:
• TOR3 configured in event mode
• Detection of high edges only
• Waiting period of 20 second
• Byte 7=0x32: register 323:
• TOR4 configured in periodic mode
• Counting of low edges only
FR
• Waiting period of 50 milliseconds
• Byte 8=0x01: register 306, Production mode in progress
In this example, given that inputs TOR1 and TOR4 are configured in periodic mode, the transmission period of the Keep Alive frame has no
impact because it is not emitted.
EN
WARNING : if none of the TOR inputs is configured (value = Disabled), the product will send the configuration frame 0x10 periodically (period
defined by register 300).

4.2.3 Network configuration data frames

Following reception of a downlink frame with the code 0x02 or on switching to the operating mode (from the Park or Command Mode), the
next frame (0x20) representing the network configuration of the product is transmitted:
0 1
Code Status
0x20 Cf Status
0x20 0x42
Description of the frame:
• Byte 2: S200 register, WMBUS channel
• Byte 3: S201 register, frame format
In the example in grey this gives:
• Byte 2=0x18: the WMBUS channel is 24
• Byte 3=0x01: the frame format is B

4.2.4 Keep Alive frame

This frame (0x30) is only issued when the different digital outputs are configured in the event mode or in output and at the frequency defined
by register 300.
0 1
Code Status
0x30 Cf Status
0x30 0xA2
As the example shows it only contains the value of the status byte.
