ECOM100 Disable DHCP (ECDHCPD) (IB-736)
ECOM100 Disable DHCP will set up 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 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).
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 the 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.
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
