This command writes the Long Type value of a specified element of an IDN to a specified drive. It is used when writing to an IDN that takes numeric values.

<element> is optional. In general, only element 7 is used (default).

This command is also used to operate a procedure command. In this case, the value 3 is written to begin the procedure, and the value 0 is written to cancel the procedure once it has completed.

Short form



WriteIdnValue Drive=<drive address>, Idn=<IDN number>, Value=<value>, {Element=<IDN element number>}

WRITEIDNVALUE Drive=<drive address> IDN=<IDN number> Value=<value {,<value>}> {Element=<IDN element number>} {Ring=<ring number>} {Connection=<connection number>}


All versions Since Version 4.7.12 for SERCOS III


<drive>: Long
<IDN number>: Long
<value>: Long
<IDN element>: Long <ring>: Long <connection>:Long


<drive>: 1 to 254
<IDN number>: 1 to 65535
<IDN element>: 1 to 7
<connection>:0 to 2 for normal systems (0 = chose automatically, 1 = first AT connection, 2 = first MDT connection)


<element>: 7
