Parameterization and commissioning
BK11x0, BK1250 55Version: 4.1
In this example program (TwinCAT 2.11, BK1120 with firmware 08), AoE and CoE register communication
with a KL3314 (thermocouple terminal) is executed in the PLC. Here, register R34 (user scaling, offset) in
Channel 1 is repeatedly incremented - success can be verified with the KS2000 software or via the
visualization page; to do this, connect a type K thermocouple to channel 1.
Note: In the startup list of the BK1120, entries are available that set the user offset to a start value at each
switch-on or INIT-OP transition.
6.3.4 Online parameterization of KL terminals via AoE
Access via AoE (ADS over EtherCAT) is useful from TwinCAT 2:11. An additional AoE NetId is required for
the coupler used, so that the TwinCAT-internal ADS router can access it. It is useful to link this AoE NetId
with the PLC program.
The same procedure is described here [}76] to access the KL terminals with the KS2000 software via ADS.
Fig.42: Activation of the AoE NetID
The AoE NetId can be generated in the advanced settings of the BK11x0/BK1250. Optionally, it can be
initialized with a pre-specified (unique!) start value.
After a TwinCAT restart it is available in the ADS router and can be used, for example, from the PLC.
The following applies to ADS accesses:
• AmsNetId: AoE NetID
• Port: 100
• IdxGrp: 0= coupler, 1.. = terminal number
• IdxOffset:
Channel IdxGrp = 0, coupler IdxGrp> 0, terminal number
