The gratuitous ARP telegrams are one way to inform a router about a modification of the MAC address bound to an IP address.ĭoes a PCD generate gratuitous ARP telegrams? If a device is replaced on a network and the new device does have the same IP address, it won't be reachable until the router (or other devices that communicate with the replaced system) refreshes the MAC address table. This telegram informs the router that there is a new IP address on the network and causes it to update its internal MAC addresses table in case the according IP was already mapped to a MAC address. Some Ethernet devices do generate gratuitous ARP telegrams every time they are connected to an Ethernet network. Does a PCD automatically generate "gratuitous ARP" telegrams? (FAQ #101045).Please note that the firmware version of both, he PCD and the BACnet module must be updated. Please update the firmware of your PCD and the one on your PCD7.R56x to the mentioned (or later) firmware versions. The firmware version 1.10.51 (for the PCD3 or the PCD2.M5) together with the BACnet firmware 1.10.50 are more robust and can cope with telegram losses during the upload of the BACnet configuration. Because of the interruption the BACnet firmware was not notified, but it remained in a state of waiting for the completion of the upload process. In case a telegram was lost (due to network problems) the transfer was interrupted by the PCD firmware. This telegram loss is random, dependent on the network load.įirmware versions before the version 1.10.51 were expecting a communication without telegram losses. ![]() This phenomenon is observed when a telegram is lost. In case a telegram got lost during upload of the BACnet configuration (from the PCD to the PC) the transfer was been aborted.ĭuring an Upload (for the function "Upload/Merge" of the BACnet configurator) all of the sudden the transfer of the configuration stops. Firmware versions before the version 1.10.51 were not supporting retries during the "Upload/Merge" process of the BACnet configurator. ![]()
