Modbus Network Adapter
The EPXMBE001 network adapter is a Modbus TCP participant
developed according to IEC 61158. The network adapter is the head
module for the RSTi-EP communication bus, to which up to 64 active
RSTi-EP modules can be connected. The Modbus TCP network adapter
has two Ethernet ports and an integrated switch.
The network adapter can be accessed with a system-independent web
server application via the USB service interface or the Ethernet. Thus, all
information, such as diagnostics, status values and parameters, can be
read and all connected modules can be simulated or forced.
The station's main power supply is integrated in the network adapter.
Power is supplied via two 4-pole connectors, separated into the input
and output current paths.
Caution, the RSTi-EP station is usually installed on a horizontally
positioned DIN rail. Installation on vertically positioned DIN rails is also
possible. However, the heat dissipation is reduced such that the
derating values change (refer to the section, Thermal Derating.
Modules should to be allowed to de-energize for a minimum 10 seconds
after power down, prior to starting any maintenance activity. The
network adapter cannot be hot-swapped.
Refer to the RSTi-EP Slice I/O User Manual (GFK-2958) for additional
information.
Refer to the RSTi-EP Power Supply Reference Guide, a software utility
available on PME V9.00, for detailed power-feed requirements.

Field Wiring
The connection frame has one connector, and two 24 V DC wires can be connected to each connector, along with two
ground connections. Those four connectors are used as shown in the following figure. The Spring style technology
allows either finely stranded or solid wire with crimped wire-end ferrules or ultrasonically welded wires, each with a
maximum cross-section of 1.5 mm² (16 guage), to be inserted easily through the opening in the clamping terminal
without having to use tools. To insert fine stranded wires without wire-end ferrules, the pusher must be pressed in with
a screwdriver and released to latch the wire.

Connector Specifications:
conductor cross-section 0.14 to 1.5 mm² (26 – 16 guage)
max. ampacity: 10 A
4-pole
The modules do not have a fused sensor/activator power supply. All cables to the connected sensors/actuators must be
fused corresponding to their conductor cross-sections (as per Standard DIN EN 60204-1, section 12).

Subject
Description
Firmware update fails when there are more
than 30 I/O modules connected to the node.
When trying to update the firmware for the analog or SIL modules using Web server,
either single module update or multiple modules update, both fail when the
connected node has more than 30 I/O modules

EP-5311 - 1 Channel SSI Encoder, BCD or Gray-Code Format, 5/24 VDC
Subject
Description
Channel diagnostics faults are reported
during hot-swap of the modules.
During hot-swap of an I/O module, the network adapter may report additional
channel diagnostics messages in addition to the expected Loss of Module or Addition
of Module fault.
Behavior during hot removal when similar
modules are configured consecutively
Where similar modules are configured consecutively in the remote I/O node, a shift in
input data occurs when one of the consecutive modules is pulled out from a node.
For example, when there are 6 RTD modules EP-3704, configured consecutively in the
node, slots 1 - 6, on hot-removal of the module from slot 4, data from modules 5 and
6 would be reflected on variables configured for slot 4 and 5, respectively, with Loss
of Module reported for slot 6.
Subject
Description
Output behavior during hotswap
During hot insertion or removal of IO modules, a transient Loss of Power up-to 500
ms may occur on the network adapter and IO modules, during which all of the
outputs may drop to zero. This system behavior should be verified against the
application requirements before hot insertion or removal of the IO module is done.
