Listed below are common parameters for primary device and subdevice.
General
- Common Address: specifies common address of the controlled station
- Device Time Zone: specifies time zone of the controlled station. This parameter is used to convert the timestamp during time synchronization and processing control and monitoring ASDUs. The default setting is [Local Time Zone], which corresponds to the local time zone of the system the server is deployed on
- Enable Reads: specifies that the driver should send a command to read C_RC_NA_1 data for all associated monitor tags with the frequency specified in the Update Rate parameter of each tag
Services
- General Interrogation (Initialization Settings): specifies whether the driver should send a general interrogation command (C_IC_NA_1) after connecting or reconnecting. The default value is Connect / Reconnect
- General Interrogation Mode (Periodic Settings): specifies whether the driver should periodically send a general interrogation command (C_IC_NA_1). The default value is Disabled
- General Interrogation Interval (Periodic Settings): defines the time interval (in seconds) for periodic sending of the general interrogation command (C_IC_NA_1). The default value is 3600
Please note that general interrogation command is generated with the qualifier of QOI = 20 (station interrogation)
- Counter Interrogation (Initialization Settings): specifies whether the driver should send a counter interrogation command (C_CI_NA_1) after connecting or reconnecting. The default value is Disabled
- Counter Interrogation Mode (Periodic Settings): specifies whether the driver should periodically send a counter interrogation command (C_CI_NA_1). The default value is Disabled
- Counter Interrogation Interval (Periodic Settings): defines the time interval (in seconds) for periodic sending of the counter interrogation command (C_CI_NA_1). The default value is 3600
Please note that counter interrogation command is generated with the qualifier of QCC = 5 (request general counter group)
- Time Sync (Initialization Settings): specifies whether the driver should send a time synchronization command (C_CS_NA_1) after connecting or reconnecting. The default value is Connect / Reconnect
- Time Sync Mode (Periodic Settings): specifies whether the driver should periodically send a time synchronization command (C_CS_NA_1). The default value is Periodically
- Time Sync Interval (Periodic Settings): defines the time interval (in seconds) for sending the periodic time synchronization command (C_CS_NA_1). The default value is 3600
- Test Mode (Periodic Settings): specifies whether the driver should periodically send a testing command (C_TS_NA_1). The default value is Disabled
- Test Interval (Periodic Settings): defines the time interval (in seconds) for sending the periodic testing command (C_TS_NA_1). The default value is 15
Listed below are the common parameters of primary device that are used to organize the data transmission channel.
Advanced
- Originator Address: specifies the client’s originator address. Takes a value from 0 to 254
- Max ASDU Size: specifies the maximum size of the generated ASDU (in bytes)
- Size of IOA: specifies the size of the the information object address (1, 2 or 3 octets). Note that all tags associated with the device whose information object address does not fit in the specified number of octets will be ignored by the driver
- Size of COT: specifies the cause of transmission field size (1 or 2 octets)
- Size of CA: specifies the size of the common address field (1 or 2 octets). Note that the parameter cannot be changed if the Common Address of the device or any of the subdevices does not fit in the specified number of octets
- Max Buffer Size: specifies the maximum number of ASDUs that the scan buffer can contain
SSL
- Use SSL: specifies whether the driver should establish a secure connection with the controlled station
- Client Certificate: specifies a client-side security certificate. Note that the certificate must contain both public and private encryption keys
- SSL Verification: contains verification mode of controlled station SSL certificate:
- Accept any.
- Verify chain of trust by using a store of certificates of the operating system
- Verify chain of trust by using custom certificate of certification authority
- Custom CA File: contains custom certificate of certification authority
