ECOM100 Disable DHCP (ECDHCPD) (IB-736)
ECOM100 Disable DHCP will setup the ECOM100 to use its internal TCP/IP settings on a
leading edge transition to the IBox. To configure the ECOM100’s TCP/IP settings manually,
use the NetEdit3 utility, or you can do it programmatically from your PLC program using
the ECOM100 IP Setup (ECIPSUP), or the individual ECOM100 IBoxes: ECOM Write IP
Address (ECWRIP), ECOM Write Gateway Address (ECWRGWA), and ECOM100 Write
Subnet Mask (ECWRSNM).
The “Disable DHCP” setting 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 first 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.
In order for this ECOM100 IBox to function, you must turn ON dip switch 7 on the
ECOM100 circuit board.
ECDHCPD Parameters
• ECOM100#: this is a logical number associated with this specific ECOM100 module in the specified
slot. All other ECxxxx IBoxes that need to reference this ECOM100 module must reference this
logical number
• 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
• Error: specifies a bit that will turn on if the instruction is not successfully completed
• Error Code: specifies the location where the Error Code will be written

N/A
The Workspace parameter is an internal, private
register used by this IBox and MUST BE
UNIQUE in this one instruction and MUST
NOT be used anywhere else in your program.
Either the Success or Error bit parameter will
turn on once the command is complete. If there
is an error, the Error Code parameter will report
an ECOM100 error code (less than 100), or a
PLC logic error (greater than 1000).
