IP network. The use of 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 explained in section 3.2.
The following list highlights the core features and functionalities provided by the MTQ22-FBP and Modbus TCP protocol. Highlighted Features 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-efficient connection of FBP devices to Ethernet.
See chapter 5 for detailed information regarding status LEDs. Figure 1: Top view of the MTQ22-FBP. Four PSE devices can be connected to the MTQ22 via the ports X1 to X4. The standard Micro USB connector X5 allows to configure the device.
X1 to X4 on the MTQ22-FBP. The Modbus master is in turn connected to one of the Ethernet connections E1 or Figure 2: Device connections required to enable a Modbus TCP connection between the PSE and a Modbus master. The cable connecting the PS-FBPA and the MTQ22-FBP, a CDP19-FBP .100 cable must be purchased separately.
This chapter describes how to configure the MTQ22-FBP and the PSE to enable Modbus communication. 3.1 PSE Softstarter The following list of instructions explains how to configure the fieldbus parameters on the PSE softstarter. Fieldbus Control This parameter is used for configuration of the fieldbus communication. Connecting the PSE Softstarter to the Fieldbus plug automatically enables fieldbus communication.

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).

Fieldbus Operation When Fault This parameter is accessible only if Fieldbus Control is previously set to On. In case of fieldbus malfunction, for instance due to power loss or a broken cable, this parameter allows for different (operations in case of a fault) reactions to the fault. Setting Fieldbus fault reaction to trIP will make the softstarter trip on a fieldbus fault.
An easy to use PC configuration tool is provided to adjust the parameters of the MTQ22-FBP. The PC can be connected to the MTQ22-FBP with a standard Micro USB-cable. The ABB Configuration Tool can be downloaded by clicking the following link or searching for 1SAJ260900R0001 at the ABB Download Center.

Set required MTQ22-FBP parameters The following steps describes how to set the required parameters on the MTQ22-FBP. After the application is started (as administrator) select the MTQ22-FBP that you want to configure in the Config Tool. From the Select port drop down menu select the COM port associated to the MTQ22-FBP and click connect.

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.
Depending on your client application it might be necessary to increment all addresses by one. The I/O-data as well as diagnostic and configuration data of the connected PSE devices can be accessed applying the supported Modbus function codes. The supported functions can be found in respective sub section.

PSE Softstarter PSE softstarter diagnostics are represented by bits in a 16-unsigned integer register. Use a calculator to translate the decimal number to one or more bits. If a bit is set that fault is active and could potentially be resetted.

If the Reset of Fieldbus Fault PSE parameter is set to Auto and the fieldbus fault (EF40) has tripped due to no communication, 30 s of stable communication is required before an automatic reset is performed.
