Product Manual — Doc. 8559B 4-Series™ Control Systems • 151
NVRAM (Nonvolatile)
Nonvolatile NVRAM contain the following components:
l
SIMPL+ variables (if "volatile" qualifier or #DEFAULT_VOLATILE is removed)
l
Signals explicitly written to NVRAM (such as Analog RAM, Analog RAM from database,
Serial RAM, Serial RAM from database, Analog nonvolatile ramp, Digital RAM, and so
forth)
NOTE: SIMPL# Pro has no access to the NVRAM. Programmers should write files for
persistent variables instead.
Console Commands
The 4-Series processor is capable of understanding and responding to a set of phrases known as
console commands. Console commands are used to configure the control system.
Observe the following about console commands:
l
Console commands can be sent to the device using an SSH client over its IP address or
host name. Console commands may also be sent to the device using the Text Console tool
in Crestron Toolbox via one of the supported communication protocols.
l
Console commands are grouped logically. Issuing the help command from the console
responds with various command categories.
l
Issuing the help all command responds with a list of all exposed console commands for
the device.
l
The same command may be listed in more than one category. Commands are case
insensitive and can be entered from the appropriate prompt.
l
To view the available options and parameters for a command, issue the command
followed by a space and "?" (for example, iptable ?).
l
Support for new console commands is added via firmware updates. Refer to the firmware
release notes for more information.
