Software and Firmware
Configuring the I/O Points
Follow the procedure listed in Chapter 6 of the OptoControl User’s Guide to add an I/O point. Notice that the
Configure I/O Points
dialog box shows 16 analog channels even though the M4RTU/M4 I/O and M4RTUX
together support a maximum of only eight analog channels. This is because the M4RTU/M4 I/O electronics
does not support the analog extender capability of an analog multifunction I/O unit. Simply ignore analog
channels 8 through 15 of the
Configure I/O Points
dialog box.
Storing User Strategies into M4RTU/M4 I/O Flash EEPROM
User OptoControl strategies may be stored into flash memory instead of residing in RAM backed up by a
battery. Flash memory has the same robust attributes of EEPROM for remote installations. Strategies may be
developed for the M4RTU/M4 I/O in RAM, remotely downloaded and debugged, and then stored remotely in
flash memory. If the M4RTU/M4 I/O has been set up to boot automatically from flash memory, the OptoControl
strategy stored in flash will be executed upon power-up.
To store an OptoControl strategy into flash memory, refer to Chapter 9 of the OptoControl User’s Guide .
To configure the M4RTU to run the program automatically from flash, refer to Chapter 3, page 35.
OPTODISPLAY AND OPTOSERVER
Both OptoDisplay and OptoServer share the database generated by OptoControl. This database contains the
configuration information for communicating to the M4RTU/M4 I/O and referencing any strategy data items,
such as variables, I/O, PIDs, and event/reactions. This information is used by OptoDisplay to dynamically drive
a given graphic’s attributes. It is also used by OptoServer to communicate to an M4RTU/M4 I/O or an Opto 22
Controller Network of M4RTU/M4 I/Os and other Opto 22 controllers.
