Controller Settings Parameters - GE PACSystems RXi User Manual

These parameters specify basic operating characteristics of the CPU. For additional details
on how these parameters affect CPU operation, refer to Chapter 5.

Controller Settings Parameters

Settings Parameters
Passwords
Stop-Mode I/O Scanning
Watchdog Timer (ms)
Logic/Configuration
Power-up Source
Data Power-up Source
Power-up Mode
Modbus Address Space
Mapping Type
GFK-2816F
Specifies whether passwords are Enabled or Disabled. Default: Enabled.
Notes: If Enhanced Security is enabled in the target properties, the Passwords
setting will be Enabled and read-only, and the Access Control tab (page 46
appears.
When passwords are disabled, they cannot be re-enabled without clearing
Controller memory.
Specifies whether the I/O is scanned while the Controller is in Stop mode.
Default: Disabled
(Milliseconds in 10 ms increments.) Requires a value that is greater than the program
sweep time.
The software watchdog timer is designed to detect failure to complete sweep
conditions. The CPU restarts the watchdog timer at the beginning of each sweep. The
watchdog timer accumulates time during the sweep. The software watchdog timer is
useful in detecting abnormal operation of the application program, which could prevent
the CPU sweep from completing within the watchdog time period.
Valid range: 10 through 2550, in increments of 10.
Default: 200.
Specifies the location/source of the logic and configuration data that is to be used (or
loaded/copied into RAM) after each power-up.
Choices: Always RAM, Always Flash, Conditional Flash.
Default: Always RAM.
Specifies the location/source of the reference data that is to be used (or loaded/copied
into RAM) after each power up.
Choices: Always RAM, Always Flash, Conditional Flash.
Default: Always RAM.
Selects the CPU mode to be in effect immediately after power-up.
Choices: Last, Stop, Run.
Default: Last (the mode it was in when it last powered down).
Notes: If the CPU does not have an Energy Pack and if Logic/Configuration
Power-up Source is set to Always RAM, the CPU powers up in Stop mode
regardless of the setting of the Power-up Mode parameter.
If Power-up Mode is set to Last and Logic/Configuration Power-up Source is
set to Always Flash or Conditional Flash, the CPU powers up in
Run/Disabled mode.
Specifies the type of memory mapping to be used for data transfer between Modbus
TCP/IP clients and the PACSystems controller.
Choices:
Disabled: The Disabled setting is intended for use in systems containing Ethernet
firmware that does not support Modbus TCP.
Standard Modbus Addressing: Causes the Ethernet firmware to use the standard
map, which is displayed on the Modbus TCP Address Map tab.
Default: Disabled
For details on the PACSystems RXi implementation of Modbus TCP server, refer to
Section 8.5, Modbus TCP Server Operation.
