Chapter 5: Intelligent Box (IBox) Instructions
ECOM100 Write Description (ECWRDES) (IB-727)
1
ECOM100 Write Description will write the given Description to the ECOM100 module on
a leading edge transition to the IBox. If you use a dollar sign ($) or double quote ("), use the
PRINT/VPRINT escape sequence of TWO
230
2
dollar signs ($$) for a single dollar sign or
240
dollar sign-double quote ($") for a double
250-1
3
quote character.
260
The Workspace parameter is an internal,
4
private register used by this IBox and MUST
DS5 Used
BE UNIQUE in this one instruction and
N/A
HPP
MUST NOT be used anywhere else in your
5
program.
Either the Success or Error bit parameter will
6
turn on once the command is complete. If
there is an error, the Error Code parameter
7
will report an ECOM100 error code (less
than 100), or a PLC logic error (greater than 1000).
8
The Description is stored in Flash-ROM in the ECOM100 and the execution of this IBox
will disable the ECOM100 module for at least a half second until it writes the Flash-ROM.
Therefore, it is HIGHLY RECOMMENDED that you only execute this IBox ONCE on the
9
second scan. Since it requires a LEADING edge to execute, use a NORMALLY CLOSED
SP0 (STR NOT First Scan) to drive the power flow to the IBox.
10
In order for this ECOM100 IBox to function, you must turn ON dip switch 7 on the
ECOM100 circuit board.

• Workspace: specifies a V-memory location that will be used by the instruction
• Success: specifies a bit that will turn on once the request is completed successfully
14
• Error: specifies a bit that will turn on if the instruction is not successfully completed
