15.1.15 echolink one2PROFINET V. 1.0 32
Softing Industrial Automation GmbH Implemented protocols in echolink one
Here the content of the address 10009 is changed from 0 -> 1
In the following example only the "No. Of Points" is switched to 10.

Which means that now 10 Bits => 2 Byte are read out. This is also the reason why the fieldbus
length byte (2. fieldbus byte) at 0x0A increases by 1 Byte.
8.8.3.3 Example: Read multiple register FC3

RX Poll Delay = 0 is automatically set to 1 by the firmware.

Modbus-Request:
Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 Byte 8
Slave ID Modbus

Low CRC High CRC Low
1 2 0x00 0x01 0 2 x y
The CRC value is automatically calculated by the echolink one
The echolink one
sends out the request (RX Poll Retry = 0) one time via the RS interface, and waits a
maximum of 250 ms (Modbus Timeout = 25) on the response.
