ECRDGWA Example
Rung 1: The ECOM100 Config IBox is responsible for coordination/interlocking of all
ECOM100 type IBoxes for one specific ECOM100 module. Tag the ECOM100 in slot 1 as
ECOM100# K0. All other ECxxxx IBoxes refer to this module # as K0. If you need to move
the module in the base to a different slot, then you only need to change this one IBox. V400
is used as a global result status register for the other ECxxxx IBoxes using this specific
ECOM100 module. V401 is used to coordinate/interlock the logic in all of the other ECxxxx
IBoxes using this specific ECOM100 module. V402-V502 is a common 130 byte buffer
available for use by the other ECxxxx IBoxes using this specific ECOM100 module.
NOTE
: An ECOM100 IBox instruction is used without a permissive contact. The top line will be identified in
BOLD italics
, and the instruction name and ID will be in
BOLD characters.
Rung 2: On the 2nd scan, read the Gateway Address of the ECOM100 and store it in V3000
thru V3003 (4 decimal numbers). The ECOM100's Gateway Address could be displayed by
an HMI.
The ECRDGWA is leading edge triggered, not power-flow driven (similar to a counter input
leg). The command to read the Gateway Address will be sent to the ECOM100 whenever the
power flow into the IBox goes from OFF to ON.
If successful, turn on C100. If there is a failure, turn on C101.
