Overview Profibus DP 2 Profibus DP 2.1 Overview Profibus is one of the most widely used automation networks in Europe. It provides a wide possible range of compatible devices while delivering fast and robust communication. Profibus offers users the option to mix devices from different companies. It is an open network ranging from simple I/O stations through to complex PLCs. The network allows extremely fast data exchange with a wide variety of slave devices.
Profibus DP Overview Transmission speeds from 9.6 kbit/s to 12 Mbit/s can be used. The maximum cable length of a bus segment is limited from 100 to 1200 m, depending on the bit rate used. With up to 3 repeaters allowed, the maximum distance between two stations is 400 to 4800 m. Cable types To help reduce costs Profibus DP uses RS 485 technology with shielded 2-wire cabling.
Head Station STL-PB1 (Profibus DP) 2.2 Profibus DP Head Station STL-PB1 (Profibus DP) The head station STL-PB1 serves as Profibus DP slave. It displays the peripheral data of all connected STlite modules on Profibus DP. Fig. 2-2: Head station STL-PB1 for Profibus DP (with connected digital input module) In the initialization phase the head station determines the physical structure of the node and creates a process image from this with all inputs and outputs.

Head Station STL-PB1 (Profibus DP) 2.2.6 Profibus DP Wiring Since RS 485 transmission technology is used, all devices are connected in a line structure. To connect the STL-PB1 to a Profibus DP network, use only the Profibus connector and shielded twisted pair Profibus cable complying with EN50170. Cable type A is strongly recommended. Parameter Specification Wave resistance Tab.
Profibus DP Head Station STL-PB1 (Profibus DP) Bus Terminator Each end of the Profibus DP network must be terminated with resistors. Since the STL-PB1 is not equipped with built-in terminating resistors, use a Profibus connector with a bus terminator if the STL-PB1 is situated at the beginning or end of a network. Fig.
Head Station STL-PB1 (Profibus DP) 2.2.7 Profibus DP Local Process Image After switching on, the head station STL-PB1 recognizes all connected STlite modules which supply data or wait for data (data width/bit width > 0).

Overview Ethernet 4 Ethernet 4.1 Overview Ethernet is unrivalled for the widest possible set of connectable technologies. While being well established in the office and IT environments, its adoption into automation environments is both rapid and broad ranging. Ethernet is a platform for a very wide range of data communications protocols. The combination of Ethernet and the extremely widespread TCP/IP protocol enables high-speed data communications between process supervision and the PLC.
Ethernet Head Station STL-ETH1 (Ethernet) Both ports support: ● 10BASE-T / 100BASE-TX ● Full / Half duplex ● Autonegotiation ● Auto-MDI(X) In order to send process data via Ethernet, the head station supports a series of network protocols. The MODBUS/TCP(UDP) protocol and the Ethernet/IP protocol are implemented for exchanging process data. The two communication protocols can be used optional or together. For the management and diagnosis of the system, the HTTP, SNTP and SNMP protocols are available.

Ethernet 4.2.3 Head Station STL-ETH1 (Ethernet) Display Elements Fig. 4-4: ETHERNET The operating condition of the head station is signalled via LEDs. LINK 1 ACT LINK 2 ACT MS NS I/O The health of the Ethernet fieldbus is signalled through the top LED group (LINK ACT 1, LINK ACT 2, MS, and NS). The two-colored LEDs "MS" (module status) and "NS" (network status) are solely used by the Ethernet/ IP protocol. These two LEDs conform to the Ethernet/IP specifications.
Head Station STL-ETH1 (Ethernet) 4.2.4 Ethernet Address Selection Switch ON 1 2 3 4 5 6 7 8 Fig. 4-5: Address selection switch of the STL-ETH1 There are two ways to allocate the IP Address to the fieldbus node: ● Manually assignment of the IP address using of the address selection switch ● Automatic assignment of addresses via a DHCP server on the network. NOTE The assignment of the IP addresses via DHCP and the changing of the static base address is not covered in this Quick start manual.
Ethernet 4.2.5 Head Station STL-ETH1 (Ethernet) Hardware Address (MAC ID) Each ETHERNET head station STL-ETH1 has a unique and internationally unambiguous physical address, referred to as the MAC-ID (Media Access Control Identity). This is located on the rear of the controller and on a self-adhesive tearoff label on the side of the controller. The MAC ID has a set length of 6 bytes (48 bits) (hexadecimal). The first three bytes identify the manufacturer.
Head Station STL-ETH1 (Ethernet) 4.2.7 Ethernet Process Data Architecture After switching on the supply voltage, the head station identifies all I/O modules connected with the node that send or receive data (data width/bit width > 0). In the maximum total extension the node can consist of a mixed arrangement of a maximum of 64 analog, digital I/O modules or special function modules connected on the head station. The data of the digital I/O modules are bit-oriented; i.e., digital data are sent bit by bit.

Likewise, data can be written to the output modules from the CPU and the fieldbus side.
Head Station STL-ETH1 (Ethernet) Ethernet Data Exchange between MODBUS/TCP Master and I/O Modules Data exchange between the MODBUS/TCP Master and the I/O modules is conducted using the MODBUS functions implemented in the controller by means of bit-by-bit or word-by-word reading and writing routines.
