Fieldbus/PROFIBUS device/network as shown in Figure 26 below. Use the provided cable clamp to secure the wires to the board. Note
that devices are connected in parallel (star fashion). For Fieldbus, a terminator (1 µF capacitor and 100 Ω resistor in series) is used on
farthest ends of the trunk (i.e., at each end of the segment cable). For details on PROFIBUS operation refer to the MT100 PROFIBUS PA
manual 06EN003474. For details on F

(JP18), #NV_ERASE (JP19), and #HW_LOCK (JP20) test signals. This provides a means to activate a "simulate mode" for Fieldbus
conformance testing and for add-on card testing/diagnostics. Enable a particular signal by installing a 0.100" jumper shunt over the
appropriate header pins. For normal use none of these jumpers are installed.
Relay Outputs
The MT100 relay interface is provided by the J11 Phoenix connector terminals. The relay connector accepts 28-16 AWG (0.14 mm
) wire. Using J11 connect the SPDT relay outputs to the appropriate external circuits as shown in Table 4 below. Relay Contact
