Sensata DHX5 IO-Link Industrial Automation Bottlenecks
ELECTRICAL INSTALLATION
RGY : Incremental OR IO-link on Z (multiplexed)
There are two different modes, by default the encoder is in incremental mode. After an IO-link WAKEUP request, the encoder switches in IO-Link mode : the Z incre-mental signal is disabled and is configured to be the IO-link C/Q pin.

Electronics RGZ : Incremental AND IO-link (simultaneous)
For this configuration, the incremental signals and IO-link are all available simultaneously.
Then the incremental signals can be incoherent few milliseconds after a configuration update from an IO-link command.

IO-LINK SPECIFICATION INFORMATION
Device specification
| Specification | IO-Link description | Value |
| Transfer rate | COM3 | 230.4 kBaud |
| Minimum cycle time of device | Minimum cycle time | 0x0A (1ms) |
| Frame specification Amount of operoperate data required Amount of operate data required Enhanced parameters | M-Sequence Capability: M-Sequence Type Operoperate M-Sequence Type Operate ISDU supported | TYPE_0 TYPE_2_V Supported |
| IO-Link protocol version | Revision ID | 0x11 (Version 1.1) |
| Amount of process data from the device to the master | Process Data In | 0x83 (4 bytes) |
| Amount of process data from the master to the device | Process Data Out | 0x00 (0 byte) |
| Manufacturer ID | Vendor ID | 0x0468 (1128) |
| Device identification | Device ID | RGY : 0x0003 RGZ : 0x0005 |
Process data
| Name | Description | Datatype | Bitoffset | Bitlength | Value Range | Unit |
| Speed | Rotating speed | IntegerT | 15 | 16 | -12000 to 12000 | rpm |
| Position | Absolute position counter | UIntegerT | 0 | 16 | 0 to 65535 |
When the absolute position resolution is configured to a value smaller than 16 bits, the data is aligned on the bit 0.
For example, if the absolute position resolution (index 90) is configured to 12 bits, the bits 0 to 11 will contain the data. Bits 12 to 15 will then be unused and set to zero.
