    • The invention relates to a an electric arc welding method, wherein an electrode assembly (100) comprises at least two fusible continuous electrodes (110, 112, 114, 116, 118) acting on a workpiece (10) for generating a weld pool (12) via electric arcs, wherein the at least two electrodes (110, 112, 114, 116, 118) are arranged in sequential order relative to a welding direction (30) and laterally separated relative to each other, wherein steps are performed of monitoring at least one stability parameter (Stab_par) for each electrode (110, 112, 114, 116, 118) of the electrode assembly (100); determining if one electrode (116) of the electrode assembly (100) violates a stability criterion (Crit); separating at least temporarily the one electrode (116) violating the stability criterion (Crit) from one or more adjacent electrodes (110, 112, 114, 118) when a violation of the stability criterion (Crit) of the one electrode (116) is detected.

    • In an Ethernet network (32), a system and method of controlling local equipment such as a multiplexer (33) that connects a plurality of subscriber lines to the network. A network processor (31) adds to an Ethernet frame, a new bit field identifying a selected subscriber line. The frame is sent to the multiplexer, which decodes and removes the new bit field, and switches the frame to the selected subscriber line. The network processor (31) may calculate a checksum (36) on the total number of bits in the Ethernet frame, including the new bit field. After removing the new bit field, the multiplexer then calculates a new checksum (43) on the bits remaining after the new bit field is removed. Alternatively, the network processor may calculate a checksum on the number of bits in the Ethernet frame, excluding the new bit field. In this case, the multiplexer switches the frame without altering the checksum.
    • 在以太网(32)中,一种控制本地设备的系统和方法,例如将多个用户线连接到网络的多路复用器(33)。 网络处理器(31)向以太网帧添加标识所选用户线路的新位字段。 帧被发送到多路复用器,其解码和去除新的位字段,并将帧切换到所选择的用户线。 网络处理器(31)可以计算包括新比特字段在内的以太网帧中的总比特数的校验和(36)。 在移除新的比特字段之后,多路复用器然后计算新的校验和(43)关于删除新比特字段之后剩余的比特。 或者,网络处理器可以计算以太网帧中的比特数的校验和,排除新的比特字段。 在这种情况下,多路复用器切换帧而不改变校验和。
