forced and/or inverted (see Main Menu > Advanced Setup > Digital I/O > Forces,
Inverted I/O).
The use of Network I/O is fairly sophisticated and generally done with the
assistance of Merrick. The PLC programming required to interface with Genetix
Network I/O is beyond the scope of this Manual. If you require assistance, please
contact the Merrick Customer Support department.
To enable Network I/O you must set this Configuration parameter to "Y". Otherwise
Network I/O will not appear in the list of Physical I/O.
Programmable IO
Programmable I/O points are Logical I/O points that can take on the characteristics
of both inputs and outputs. They have no inherent logical functionality, but are
generally used to "connect" inputs to outputs. For example one Physical input may
be mapped to multiple Programmable I/O points, each of which may in turn be
mapped to multiple Physical outputs. In this example, if the Physical input turns on,
all the Physical outputs so mapped would also turn on.
Because Programmable I/O points are Logical I/O, they can also be set for
Warning or Fault ((see Main Menu > Advanced Setup > Digital I/O >
Warnings/Faults).
The use of Programmable I/O is fairly sophisticated and generally done with the
assistance of Merrick. Many things are possible, beyond the simple example
shown above; however a complete discussion is beyond the scope of this Manual.
If you require assistance, please contact the Merrick Customer Support
department.
To enable Programmable I/O you must set this Configuration parameter to "Y".
Otherwise Programmable I/O will not appear in the list of Logical I/O.
Expansion Analog Card 1
Some Genetix controllers are provided with an auxiliary analog card that can either
be plugged into the expansion header on the GCM as a daughtercard, or panel
mounted and connected to the GCM via a cable. Each such card card provides for
2 additional analog outputs, one additional analog input, and 4 additional digital
inputs (dry contact). There can be a maximum of two Expansion Analog cards.
If you have such a card, this feature must be turned on to enable it. Once enabled,
the additional I/O will appear in the menus.
Expansion Analog Card 2
If you have a second Expansion Analog card, this feature must be turned on to
enable it (see above).
