PROFIBUS MODULE (CB15/CB155) English Operating Instructions Warning and Caution Notes WARNING Hazardous voltages are present in this electrical equipment during operation. Non-observance of the safety instructions can result in severe personal injury or death. Only qualified personnel should work on or around this equipment after becoming thoroughly familiar with all warnings, safety notices and maintenance procedures contained herein. -
Page 5: Overview
Operating Instructions 1. OVERVIEW 1.1 Description and Features The PROFIBUS Module (CB15/CB155) is a device that allows control of an inverter over a PROFIBUS-DP (SINEC L2-DP) serial bus. Features Retains the ability to access the internal parameter set of the inverter (CB15 only). - Page 6 Each word in the frame is assigned a fixed function. The CB15/CB155 supports the PROFIBUS-DP control commands FREEZE and SYNC. A diagnostics parameter can be used to read detailed diagnostics information straight from the diagnostics memory...

Connections to this socket are as follows: Pin 3 PROFIBUS P connection... -
Page 9: Cb155 Terminals
PROFIBUS MODULE (CB15/CB155) English Operating Instructions 2.2.1.2 CB155 Terminals The PROFIBUS connection will normally be made using the optional T connector 6SE9996-0XA21 ). This is connected to the free connector on the side of the CB155, and is in turn screwed to the front of the CB155, thus providing the PROFIBUS IN and OUT connections. -

Set to ‘0’ and then press P to reset all parameters except P101 to the settings factory default settings. 3.3.3 Hex Display for PROFIBUS on CB15 Several PROFIBUS-DP parameters are displayed in hex format using the four digit 7-segment display on the inverter. -
Page 14: Fault Codes
4. FAULT CODES Fault codes are displayed and acknowledged for the CB15/CB155 in the same way as on the inverter. Several new error codes specific to PROFIBUS have been added and are described below. Further help may be found in section 5 (PROFIBUS Commissioning) and section 6 (PROFIBUS Troubleshooting). -

PROFIBUS MODULE (CB15/CB155) English Operating Instructions Parameter Value (PWE) (3rd and 4th Word) The parameter value (PWE) is always transmitted as a double word (32 bits). Only one parameter value can be transmitted in a frame. A 32-bit parameter value is composed of PWE1 (most significant word, 3rd word) and PWE2 (least significant word, 4th word). -

Page 22: Watchdog Timeout
(see section 5.1.2.3) . 5.1.3 Watchdog Timeout When communication starts, the PROFIBUS-DP master transmits a value t WD to the CB15/CB155 for the watchdog. The watchdog on the unit is activated or deactivated according to the transmitted value. When the watchdog is active, the CB15/CB155 monitors communication with the PROFIBUS-DP master. -

COM ET 200 software are included in the COM ET 200 software manual. Note that the Class 2 master may also be used without the IM308B/C being enabled on the bus. The Class 2 master may also be connected directly to the D-type connector on the CB15/CB155 if desired. WARNING When using a Class 2 master to control a slave device, the PROFIBUS watchdog is not enabled.
