ComAp offers a wide range of options to connect to your controller:
Note that some connection types require you to use a communication module (plug-in eg a RS232 card) or communication bridge (external device eg Internet Bridge NT).
You can download the latest firmware package on the webpage of the device. You can easily navigate there through the ‘Products’ section or just use the Search function. If you cannot find the firmware on the website or if you require different than the offered version do not hesitate to contact our support team.
The firmware upgrade itself is easy to perform. You need the appropriate configuration software and a connection to the controller (preferably a direct connection). Prior to initiating the update process, we strongly recommend you to save a complete backup of your device.
It usually consists of several steps:
Should you be unsuccessful in programming the new version, the rollback procedure is to install previous firmware version and use your back up to restore the controller to its original state before the firmware upgrade was attempted.
SPtM = Single Parallel to Mains
MINT = Multiple gen-sets with INTernal sync and load sharing
MGCB = Master Generator Circuit Breaker
ComAp’s world is full of abbreviations but once you get a basic understanding of their meanings, you will find them useful when reading the documentation or communicating with us.
The full list of abbreviations is located here: https://www.comap-control.com/support/tools/list-of-abbreviations .
If you have forgotten your controller password, it can be found using the password decode function.
You will need the following information about your device:
Once you have these numbers, please contact your ComAp distributor and they will help you get your password back.
Yes, ComAp devices are capable of communication with electronic engine control units (ECUs) from the majority of engine manufacturers.
Typically, you connect the ECU directly to the controller using CAN bus. If the ECU does not support the J1939 communication protocol you need to use a communication interface either on the ECU side (such as SAM CCB2 or SmartConnect modules) or on the ComAp side using the I-CB communication bridge.
The communication is typically bi-directional so we support reading of values from the ECU as well as sending commands to the ECU (Start, Stop, etc) and controlling the engine RPM.
For details including physical connection, configuration steps and troubleshooting help please consult the Electronic Engines Support Guide available on this website.
Usually connecting to the controller over the internet is straightforward and works out of the box. However, there are a few parameters that need to be set correctly.
The ComAp product portfolio includes controllers that can control voltage and speed and with those products our controllers are able to synchronise to the mains.
Synchronizing a gen-set to mains (or multiple gensets to each other) is a procedure which requires the following conditions to be met before you connect the two electrical systems together:
The last condition is predetermined by wiring and needs to be checked prior to commissioning, the rest can be controlled by a ComAp device. In order to do so you need to interface the generator AVR (Automatic Voltage Regulator) and the engine Speed Governor. ComAp controllers designed for paralleling operations typically have outputs designed for this connection. Thanks to this we are able to control the generator voltage and the engine speed (and subsequently phase angle).
The procedure of configuring the speed and voltage regulation is described in the relevant documentation.
The same document also contains the list of supported AVRs and Speed Governors including the wiring and configuration setpoints.
The C stands for Communications. The NTC version contains extra USB, Ethernet and RS485(2) ports.
Yes, the controller application (single gen-set, multiple gen-sets, island operation, parallel to mains operation) can be changed using the controller configuration software.
AirGate allows our controllers to connect to the internet using existing network infrastructure, negotiating firewalls and VPN systems and removing the requirement for static and public IP addresses.
ComAp controls incorporate the AirGate connection technology to make access to the internet as simple as possible. AirGate was designed to overcome the issues commonly faced when trying to connect remote equipment using internet based communications.
AirGate allows our controllers to connect to the internet using the existing network infrastructure, negotiating firewalls and VPN systems and removing the requirement for static and public IP addresses.
Once AirGate in the controller is activated even if the IP address is changed, our configuration and monitoring tools will keep track of the remote equipment.
The controller firmware does not usually break by itself however it can be damaged during controller programming, typically if power is lost during the process. If there does not seem to be a hardware issue with the controller there is an option to restore the controller using a process called ‘Boot Jumper’ programming.
This can be described as a sequence of steps you need to perform to allow the configuration tool to write new firmware into the device.
The steps typically are:
The description above is not enough? Try our Booot jumper training video.
You can export the list of MODBUS communication objects directly from the controller.
In order to do this, you need to connect to the controller using the appropriate software (or use an offline archive).
LiteEdit: When you are connected to the controller or have its archive open in LiteEdit please click on: Controller -> Generate Cfg Image -> Generate Cfg Image (Modbus registers - used)...
GenConfig: When you are connected to the controller or have its archive open in GenConfig please click on: File -> Generate Cfg Image -> Generate Cfg Image (Modbus registers - used)…
InteliConfig: When you are connected to the controller or have its archive open in InteliConfig please click on: Tools -> Generate Cfg image (MODBUS)
In order to get SNMP MIB table just replace the last part with "Generate SNMP MIB table…"
This way you will get an exact list of registers which is based on the actual controller configuration.
For further reference please look into the Communication Guide which describes all MODBUS related details.
The vast majority of all issues related to CAN bus come from incorrect wiring.
