| − | == Modbus IP Server Configuration ==
| + | [[https://support.coolautomation.com/hc/en-us/article_attachments/12455777507485 Modbus Integration Guidelines]] |
| − | CoolMasterNet Modbus IP Server is activated with below command:
| |
| − | {{Terminal|
| |
| − | >'''modbus IP enable'''<br>
| |
| − | OK, Boot Required!<br>
| |
| − | >}}
| |
| − | CoolMasterNet has to be restarted to run Modbus IP server for the first time. Same way Modbus IP server can be disabled, in this case instead of '''enable''' type '''disable'''<br>
| |
| − | To quire current Modbus IP server configuration use '''modbus''' command without parameters:
| |
| − | {{Terminal|
| |
| − | >'''modbus'''<br>
| |
| − | ModBus IP : enabled<br>
| |
| − | server port : 502<br>
| |
| − | CG4 ignore : none<br>
| |
| − | OK<br>
| |
| − | >}}
| |
| − | Modbus IP default TCP/IP port is 502. This is one of the so called well-known Ethernet ports. If required, port number can be changed with:
| |
| − | {{Terminal|
| |
| − | >'''modbus server port 500'''<br>
| |
| − | OK, Boot Required!<br>
| |
| − | >}}
| |
| − | Again restart required to let port change take effect. Modbus IP Server configurations are persistent over power resets, they are stored in nonvolatile memory.

| − | == Virtual Address (VA) Concept ==
| |
| − | In order to simplify translation of the UID (like '''L5.102''') into Modbus object address, CoolMasterNet uses VA, associated with UID. Each UID can have none, one or a number of associated VA's. VA's are plain numbers starting from 001 (decimal). To let CoolMasterNet automatically associate VA's with existing (visible with '''ls''' command) UID's run:
| |
| − | {{Terminal|
| |
| − | >'''va auto'''<br>
| |
| − | OK<br>
| |
| − | >}}
| |
| − | This command will delete all existing associations and will create new associations one to one (one VA to one UID). At any time VA associations list can be retrieved with plain '''va''' command:
| |
| − | {{Terminal|
| |
| − | >'''va'''<br>
| |
| − | L1.101 --> 001 [Hex: 0x0011 | Dec: 00017]<br>
| |
| − | L1.102 --> 002 [Hex: 0x0021 | Dec: 00033]<br>
| |
| − | L1.103 --> 003 [Hex: 0x0031 | Dec: 00049]<br>
| |
| − | L1.104 --> 004 [Hex: 0x0041 | Dec: 00065]<br>
| |
| − | L1.105 --> 005 [Hex: 0x0051 | Dec: 00081]<br>
| |
| − | OK<br>
| |
| − | >}}
| |
| − | Hex and Dec numbers printed after VA are Base Address used to access Modbus objects related to UID-VA association. Base Address can be calculated as '''''BaseAddress = VA*16 + 1'''''. For example Indoor Unit L1.102 has associated VA = 002, thus Base Address = 2*16+1 = 33.

| − | Once the Base Address is determined, access to the specific Indoor Unit parameter(s) is done via Modbus objects listed below.
