IP datagrams removes the need for slave addresses since all slaves use a unique IP address to enable IP communication. However, The MTQ22-FBP still uses Modbus RTU to communicate with the PSE which require the slave ID to match between the MTQ22-FBP and the PSE, as ex- plained in section 3.2.
– The MTQ22-FBP Ethernet adapter module provides Ethernet connectivity for the ABB PSE softstarter Fieldbus plug (FBP) device. – Up to four FBP devices can be connected to one MTQ22-FBP. This allows a very cost-effi- cient connection of FBP devices to Ethernet.
2.2. MTQ22-FBP A device layout of the MTQ22-FBP can be seen in Figure 1. Connectors X1 ... X4 are used to connect up to four FBP devices to the MTQ22-FBP. On the left side of the port connectors LEDs show the current communication status. See chapter 5 for detailed information regard- ing status LEDs.
Fieldbus Plug Accessory (PS-FBPA) as seen in Figure 2. Further the PS-FBPA must be con- nected to one of the ports named X1 to X4 on the MTQ22-FBP. The Modbus master is in turn connected to one of the Ethernet connections E1 or E2.
F I ELD BU S CO MMU N ICAT ION Software Configuration This chapter describes how to configure the MTQ22-FBP and the PSE to enable Modbus com- munication. 3.1. PSE Softstarter The following list of instructions explains how to configure the fieldbus parameters on the PSE softstarter.

F I ELD BU S CO MMU N ICAT ION 3. Fieldbus Type The fieldbus type parameter must be set to FbP (fieldbus plug) when using the MTQ22-FBP. FbP is the default value of the parameter. The PSE has a built-in version of Modbus which is activated by setting the parameter to Int (Internal).
(2) is used. On the PC the MTQ22-FBP configuration software must be installed (3). If the MTQ22-FBP is connected for the first time the required USB driver has to be installed. The Microsoft USB driver is not part of the software package because of license reasons. It is pre-installed on Windows 7 and 10, for XP it must be downloaded separately from Microsoft.

1. After the application is started (as administrator) select the MTQ22-FBP that you want to configure in the Config Tool. 2. From the Select port drop down menu select the COM port associated to the MTQ22-FBP and click connect. The number of the COM port varies, make sure to select the one con- nected to the MTQ22-FBP.

Device address read by the MTQ22-FBP. When the two Device addresses match for all connected PSEs click the Write to MTQ22-FBP button again. Note that, when the slave ID is updated in the PSE a reboot will be required on the PSE for the Config Tool to the detect the new value.
Modbus TCP Register Map The following chapter shows how to generally access data of the FBP-devices connected to port one to port four of the MTQ22-FBP. Information Modbus TCP counts registers beginning with one. But on the bus registers start counting from zero.
230Ah Run time in hours 4.4. Parameters The MTQ22-FBP does not support reading or writing PSE softstarter parameters such as start ramp time, initial voltage and torque control. 4.5. Diagnostics To read the diagnostics data, use Modbus function code 3 Read Holding Registers or 4 Read Input Registers.
F I ELD BU S CO MMU N ICAT ION MTQ22-FBP LED Diagnostics in Case of Error Diagnostic information is locally displayed using two Light Emitting Diodes (LEDs) per PSE device interface. The meaning of the LEDs is as follows.
