Safety instructions

Target audience

Helmholz TAP IE 100 Ethernet Test Access Point User Guide  & troubleshooting 3This description is only intended for trained personnel qualified in control and automation engineering who are familiar with the applicable national standards. For installation, commissioning, and operation of the components, compliance with the instructions and explanations in this operating manual is essential. The specialist personnel is to ensure that the application or the use of the products described fulfills all safety requirements, including all applicable laws, regulations, provisions, and standards.

Intended use
Helmholz TAP IE 100 Ethernet Test Access Point User Guide  & troubleshooting 4 The device has a protection rating of IP 20 (open type) and must be installed in an electrical operating room or a control box/cabinet in order to protect it against environmental influences. To prevent unauthorized operation, the doors of control boxes/cabinets must be closed and possibly locked during operation. The consequences of improper use may include personal injury to the user or third parties, as well as property damage to the control system, the product, or the environment. Use the device only as intended!

Operation

Helmholz TAP IE 100 Ethernet Test Access Point User Guide  & troubleshooting 5 Successful and safe operation of the device requires proper transport, storage, setup, assembly, installation, commissioning, operation, and maintenance. Operate the device only in flawless condition. The permissible operating conditions and performance limits (technical data) must be adhered to. Retrofits, changes, or modifications to the device are strictly forbidden.

Introduction

The TAP IE 100 enables the recording of Ethernet communications at 10 or 100Mbps without retroactive effect. The Ethernet transmission via the Line RJ45 sockets is sent out on the two monitor sockets as a “copy”. With a PC or other diagnostic device, the Ethernet telegrams can be logged and analyzed, e.g. with “Wireshark”. The practical flat design with the intelligent arrangement of the network connections saves space in the control cabinet.

The network line is looped through the TAP IE 100 without feedback (“LINE 1” / “LINE 2”). The monitor RJ45 socket (“MON 1/”MON 2”) sends the data out separately from the communication partners.

The transmission between the two communication partners works even if the TAP IE 100 is not supplied with voltage or if no cables are connected to the monitoring sockets. Connecting or disconnecting the monitoring cables or the diagnostic device has no effect on the communication via the LINE sockets.

Connecting the TAP IE 100

Helmholz TAP IE 100 Ethernet Test Access Point User Guide  & troubleshooting 8

The power supply of the TAP IE 100 must be supplied with 24 VDC via the supplied connector plug at the “-/+” wide range input (18 – 30 VDC).

Helmholz TAP IE 100 Ethernet Test Access Point User Guide  & troubleshooting 9 The housing of the TAP IE is not grounded. Please connect the ground terminal of the TAP IE properly to the reference potential.

The RJ45 sockets “LINE 1” and “LINE 2” are used to connect the network participants. Use the TAP IE 100 either directly at the PLC or the host computer to be able to record all communication processes. Alternatively, the TAP IE 100 can be used directly at the station that is to be specifically examined.

The sockets “LINE 1” and “LINE 2” are physically connected to each other. The Ethernet transmission is not influenced. For this reason, the two RJ45 sockets also have no status LEDs! Please note that the total length of the cable connections between the subscriber at LINE 1 and the subscriber at LINE2 must not exceed the maximum cable length allowed for Ethernet (usually <100m).

Helmholz TAP IE 100 Ethernet Test Access Point User Guide  & troubleshooting 10 The connection of the Ethernet cables to “MON 1” and “MON 2” and the diagnostic device as well as the power supply of the TAP IE 100 can also be omitted during the initial installation of the TAP IE 100 and only carried out if required. The connection of the cables is also retroactive.

Commissioning and use

Helmholz TAP IE 100 Ethernet Test Access Point User Guide  & troubleshooting 11

If the Ethernet telegram traffic is to be read, a diagnostic device must be connected via the monitor sockets.

To do this, connect the RJ45 sockets “MON 1” and “MON 2” to the diagnostic PC or the diagnostic device using two standard 100MBps Ethernet cables. The diagnostic PC or the diagnostic device must have two network connections for differentiated reading of the Ethernet frames.

Via “MON 1” the Ethernet frames of transmission direction “LINE 1” and via “MON 2” the frames of the other transmission direction “LINE 2” are decoupled and sent as standard Ethernet frames to the diagnostic device.

Helmholz TAP IE 100 Ethernet Test Access Point User Guide  & troubleshooting 12 If the auto crossover function is used between the communication partners, the monitor sockets may output the telegrams from the transmitters crosswise “LINE 1” to “MON 2” and “LINE 2” to “MON 1”. Either switch off the auto crossover during installation or swap the cables at “MON 1” and “MON 2”.

Any Ethernet analysis software can be used on the diagnostic PC, but it must support two network connections. As an example, the free software “Wireshark” may be mentioned here.

Helmholz TAP IE 100 Ethernet Test Access Point User Guide  & troubleshooting 13 If the TAP IE 100 is already installed during commissioning of the plant, the Ethernet communication can be analyzed without changing the running machine in case of service. We recommend early installation of the TAP IE 100 in critical applications where it is not possible or difficult to switch off the system or the communication line during operation.

Helmholz TAP IE 100 Ethernet Test Access Point User Guide  & troubleshooting 14 In the current version, the TAP IE 100 does not always support the recording of transmissions with activated “EEE” (Energy Efficient Ethernet). It is possible that the connection with the diagnostic device cannot always be established. However, “EEE” is not usually used in the automation environment.

Diagnostics via LEDs

The TAP IE 100 has a Power-Led (PWR) and 4 LEDs at the RJ45 monitor jacks. The RJ45 LINE jacks have no LEDs because the transmission signal between the jacks should not be influenced. The green PWR LED indicates a functioning power supply. With the correct voltage supply, the RJ45 sockets “MON 1” and “MON 2” are also functional.

Helmholz TAP IE 100 Ethernet Test Access Point User Guide  & troubleshooting 15 The transmission between the two communication partners via the LINE sockets also works if the TAP IE 100 is not supplied with voltage! The voltage supply is only necessary if a diagnostic device is connected to the monitor sockets.

The LEDs at the RJ45 sockets “MON 1” and “MON 2” indicate the Ethernet transmission to the diagnostic device. For technical reasons, only the green led on each RJ45 socket has a function. The green LED lights up or flashes as soon as Ethernet telegrams are transmitted to the diagnosis device via the respective RJ45 socket. The LEDs only light up or flash when the TAP IE 100 is supplied with voltage and a diagnostic device is connected to the monitor sockets.
