6.3 Hardware Selftest
During power-on the 4x50 ethernet system unit will perform a hardware selft-
est. The test will cause the light emitting diodes D1, MS and NS to flash short-
ly one at a time.
6.4 Update times
The 4x50 Ethernet system unit samples the load cell signals over a period of 20
ms, 100 ms, 200 ms or 400 ms. The hereby found load cell signals are used in
the EtherNetIP communication until new signals are achieved when the next
sample period expires. Update times across the EtherNetIP communication de-
pends on the specific EtherNetIP configuration (switches, number of units, mas-
ter scan times etc.) and are beyond the scope of this document.
