SYNRAD FH Series Flyer Operator’s Manual Version 3.4

Ethernet conguration

 On the “Device” tab, set the External Communications Server property to “Modbus”.

 SynComm listens on the default Modbus port (502).

 Modbus is a big endian protocol (Modbus.h and Modbus.c contain endian conversion routines to aid

in parsing data).

 Modbus is a request/reply (master/slave) protocol. FH Flyer is set to be a Modbus slave device (server).

Note: For customers who wish to write applications where the Flyer marking head is the only device on

the network, use the SynComm Modbus-Asynchronous protocol. The Modbus-Asynchronous

protocol provides additional features that are not part of the standard Modbus/IP protocol such as

I/O events, log messages, and intermediate end of mark messages.

 All character strings must be null terminated (designated as “\0” in this document). String length

routines do not include the null character as part of string length so you must account for this when

parsing data.

 All le uploads and downloads to the Flyer Filestore are done through FTP via an FTP server on the

marking head.
