H0-PSCM, H2-PBC and T1H-PBC Information

Profibus is a control bus that provides a common method to connect automation equipment with devices on a single network. This standard communications media is referred to as Profibus and significantly reduces hardwiring costs. Profibus provides specifications for information exchanged between nodes, such as controller data associated with low-level device and configuration parameters individually related to system operations. Profibus allows 32 stations per segment. Segments vary in length depending on the desired transmission speed. The maximum speed is achieved on a segment 100 meters (327 feet) in length. Each of our Profibus DP Slaves represents a single station. Repeaters also count as stations and are used to extend the network to greater distances. Our Profibus modules support baud rates of 9.6Kbaud to 12Mbaud depending on the network length.

The H0-PSCM (Profibus Slave Communication Module) allows you connect a DL05 or DL06 PLC to a Profibus-DP network. This module plugs into the option slot of the DL05 or DL06 PLC and gives the Profibus master direct control over the PLC's internal memory and I/O. The module allows the user to transfer word and/or bit data to and from a DL05 or DL06 PLC to the Profibus master on a continuous basis, (every scan). The GSD file defines the operational modes and capabilities and the type of I/O that the module supports. Using this GSD file, the user will define:

How many blocks of data, ( up to four )

The type of each block, ( Input or Output, and BIT or WORD ). Possible choices of data types being X, Y, C, S, T, CT, GX, GY, & V for bit operations and V for word operations.

The size of each data block. Block sizes for words can be from 1 to 32 words. Block sizes for bits can be from 8 to 64 bits. The block size increments for both words and bits are defined by the GSD file and can not be changed by the user.

The address of the data to be operated on.

(Retired) The H2-PBC (Profibus Base Controller) allows you to connect DL205 I/O to a Profibus network. This module plugs into the CPU slot of any DL205 base and supports all of the discrete and analog I/O currently available as well as the H2-CTRIO module.

(Retired 8/2020) The T1H-PBC (Profibus Base Controller) allows you to connect Terminator I/O to a Profibus network. The T1H-PBC supports all of the discrete and analog I/O currently available as well as the T1H-CTRIO module.
