Note
Process data monitoring
•
WcState
: if ≠ 0, this EtherCAT device does not take part in the process data traffic
•
State
: if ≠ 8, the EtherCAT device is not in OP (operational) status
•
TxPDO state, SyncError:
if ≠ 0, then no valid process data are available, e.g. caused
by broken wire
•
TxPDO Toggle
: if this bit is toggling, a new set of process data is available
EtherCAT cycle time
For the EL5101 a minimum EtherCAT cycle time of >100 µs is recommended. If a faster cycle time is used,
the toggling process record
TxPDO Toggle
should be used to monitor when new process data are supplied
by the EL5101.
EL5101 input impedance
The signal source must be able to operate the input impedance of the EL5101 (typically 220 Ω, subject to
modification) with adequate voltage levels according to RS485.
Gate/latch input
For gate and latch inputs (24 V) a max. input frequency of 1 MHz is permitted. Subject to modification.
Level on interface
In differential mode the EL5101-00xx expects the signal levels after RS422. The data are transferred without
ground reference as voltage difference between two cables (signal A and inverted signal /A). The terminal
analyses signal levels in the range -200 mV < Vid < +200 mV as valid signals. The differential signal must be
in the common mode range (<+13.2 V and >-10 V, with respect to GND) (cf. diagram). Signal levels outside
this range can lead to destruction.
