IOT-GATE-RPI4 I/O Configuration
Contents
Overview
This article provides instructions for iotg-rpi4-config utility. It's a command-line interactive tool for configuring IOT-GATE-RPI4 peripherals and Industrial I/O modules.
The utility is part of IOT-GATE-RPI4 OS Configuration Layer.
Running utility
|
IOT-GATE-RPI4 configuration settings made by iotg-rpi4-config are propagated into config.txt file and require a reboot to take effect. |
Please run the iotg-rpi4-config with root permissions:
pi@raspberrypi:~$ sudo iotg-rpi4-config
Use the Up and Down arrow keys to move through menu options, Enter to move in and Esc to move out.
Use Space to select/deselect configuration option.
Use Tab to jump between menu body and control buttons (e.g. Select, Back etc.)
Main Menu
Main menu provides access to main options:
┌─────────────┤ IOTG-RPi4 Configuration Tool (iotg-rpi4-config) ├──────────────┐ │ │ │ 1 Peripherals Peripheral devices options │ │ 2 Industrial I/O modules Industrial I/O modules options │ │ 3 Save Changes and Exit Apply changes and exit │ │ 4 Discard Changes and Exit Exit discarding changes │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ <Ok> <Cancel> │ │ │ └──────────────────────────────────────────────────────────────────────────────┘
Configure Peripheral devices
IOT-GATE-RPI4 features an optional on-board Trusted Platform Module which can be enabled/disabled via this menu.

TPM is mutually exclusive with I/O slot D |

Configure Industrial I/O Modules
For each industrial slot user is allowed to choose one of following configuration option:
- Keep (default) - try to preserve a slot configuration currently stored in the config.txt Should be used to avoid unnecessary explicit configuration
- Detect - detect a currently plugged industrial I/O module type and store in the config.txt. Used if I/O module has been installed, but hasn't been configured yet
- CAN - configure CAN interface on a slot regardless of a a currently plugged module type.
- RS232 - configure RS232 interface on a slot regardless of a currently plugged module type
- RS485 - configure RS485 interface on a slot regardless of a currently plugged module type
- IO - configure Digital I/O module on a slot regardless of a currently plugged module type. Affects a neighbor slot as well because Digital I/O module takes two slots
- Empty - disable any slot configuration in the config.txt regardless of a currently plugged module type.
- Deactivate - detect a currently plugged industrial I/O module type and store in the config.txt as a commented line (best efforts). May be used for example to
Specific I/O module type options (CAN, RS232, RS485, IO, Empty) are usually used when different I/O module (or no one) is currently installed, but user wants to replace it with different one.
┌──────────────────────────┤ Industrial I/O Slot A ├───────────────────────────┐ │ │ │ ( ) Keep Keep current module configuration unchanged │ │ ( ) Detect Detect currently plugged module type: [Empty] │ │ (*) CAN Configure CAN interface │ │ ( ) RS232 Configure RS232 interface │ │ ( ) RS485 Configure RS485 interface │ │ ( ) IO Configure Digital I/O - dual slot │ │ ( ) Empty Skip module type configuration │ │ ( ) Deactivate Detect currently plugged module type but leave inactive │ │ │ │ <Ok> <Cancel> │ │ │ └──────────────────────────────────────────────────────────────────────────────┘

iotg-rpi4-config utility makes best efforts to apply user defined configuration. But result is not guaranteed because not any user configuration is applicable |
User defined configuration can be shown in a corresponding menu.

┌────────────────┤ Show Industrial I/O Modules Configuration ├─────────────────┐ │ │ │ D1 Show User Configured Show user defined configuration │ │ D2 Show Detected Show currently detected configuration │ │ │ │ │ │ │ │ │ │ │ │ <Select> <Back> │ │ │ └──────────────────────────────────────────────────────────────────────────────┘
Detected modules
This option displays industrial I/O slots and detected I/O modules
┌──────┤ Industrial I/O modules detected ├───────┐ │ │ │ Slot A: [Empty] │ │ │ │ Slot B: [Empty] │ │ │ │ Slot C: [IO] │ │ │ │ Slot D: [IO] │ │ │ │ │ │ <Ok> │ │ │ └────────────────────────────────────────────────┘
User defined configuration
This option displays user defined configuration for industrial I/O slots and underlying modules
┌──────────┤ Industrial I/O modules: user defined configuration ├──────────────┐ │ │ │ Slot A: [CAN] - Configure CAN interface │ │ │ │ Slot B: [Keep] - Keep current module configuration unchanged │ │ │ │ Slot C: [Detect] - Detect currently plugged module type │ │ │ │ Slot D: [Detect] - Detect currently plugged module type │ │ │ │ │ │ <Ok> │ │ │ └──────────────────────────────────────────────────────────────────────────────┘
Save Changes
It's strongly recommended to review user defined configuration for I/O modules before applying a new configuration.
