DirectLOGIC 205 (DL205) PLC - Remote I/O
- Ethernet
With the DL205 programmable logic controller
(PLC), remote I/O applications are easy to do with remote I/O bases that
can be located up to 1,200 meters (at 19.2 K baud) from the local base.
We offer both serial and Ethernet Remote I/O master and slave modules.
Ethernet products include those listed below.
The Ethernet Remote Master H2-ERM(-F) connects
240, D2-250, 250-1 and 260 CPU systems to slave I/O over a high-speed
Ethernet link. The H2-ERM can also be used in a WinPLC system, but only
one H2-ERM can be used with one slave per system.
Each ERM module can support up to 16 additional
H2-EBC systems, 16 Terminator I/O EBC systems, or 16 fully expanded H4-EBC
systems. Of course, combinations are fine, too. The ERM also supports
Edrives. (Click on the Drives product category for details).
NOTE: Applications requiring an extremely large number of T1H-EBC
analog I/O or H4-EBC 16-channel analog I/O, could exceed the buffer capacity
of a single H2-ERM module. In these cases, an additional H2-ERM may be
required.
The ERM connects to your control network
using Category 5 UTP cables for cable runs up to 100 meters. Use repeaters
to extend distances and expand the number of nodes. Our fiber optic version
uses industry standard 62.5/ 125 ST-style fiber optic cables and can be
run up to 2,000 meters.
The PLC, ERM and EBC slave modules work
together to update the remote I/O points. These three scan cycles are
occurring at the same time, but asynchronously. It is recommended that
critical I/O points that must be monitored every scan be placed in the
CPU base.
Networking ERMs with other Ethernet devices
It is highly recommended that a dedicated Ethernet remote I/O network
be used for the ERM and its slaves. While Ethernet networks can handle
a very large number of data transactions, and normally handle them very
quickly, heavy Ethernet traffic can adversely affect the reliability of
the slave I/O and the speed of the I/O network. Keep ERM networks, multiple
ERM networks and ECOM/ office networks isolated from one another.
Software configuration
ERM Workbench is a software utility that must be used to configure the
ERM and its remote Ethernet slaves. ERM workbench supports two methods
of configuring the ERM I/O network:
- ERM Workbench PLC Wizard greatly simplifies
the configuration procedure when a PLC is used as the CPU interface.
- ERM Workbench configures the I/O network
whether the CPU interface is PLC or WinPLC, and allows access to all
ERM I/O network parameters.
Ethernet remote I/O kits
We've added these Ethernet remote I/O kits to make it easier for you to
set up remote I/O via Ethernet. These kits contain parts that are already
offered separately, but we've combined them in kits to make it simpler
to order the remote I/O product configurations you need.
- H2-ERKIT-x
Ethernet Remote I/O Kit, includes (1) H2-ERM plus "x" number of H2-EBCs
by adding -1, -2, etc. as the part number suffix.
Ethernet Remote I/O for a 10Base-T Ethernet network at 10 Megabaud,
cable not included. H2-ERM must be installed in a local base, with a
D2-240, D2-250(-1), D2-260 or H2-WPLCx-xx in the CPU slot. Ethernet
cable connects to H2-EBCs directly or via Ethernet hub(s).
- T12-ERKIT-x
Ethernet Remote I/O Kit, includes (1) H2-ERM plus "x" number of T1H-EBCs
by adding -1, -2, etc. as the part number suffix.
Ethernet Remote I/O for a 10Base-T Ethernet network at 10 Megabaud,
cable not included. H2-ERM must be installed in a local base, with a
D2-240, D2-250(-1), D2-260 CPU or H2-WPLCx-xx in the CPU slot. Ethernet
cable connects to T1H-EBCs directly or via Ethernet hub(s).

Use EBCs for PC-based control and for
H*-ERM remote I/O slaves
The H2-EBC, H2-EBC100, H2-EBC-F, T1H-EBC and T1H-EBC100 Ethernet Base
Controller modules (EBCs) provide a low-cost, high-performance Ethernet
link between DL205 I/O and your PC-based control system or WinPLC/ DL205/
DL405 CPUs using the H*-ERM module for remote I/O. The H2-EBC100 can also
be used to connect your DL205 I/O to a MODBUS TCP/IP client (master).
The H2-EBC and T1H-EBC modules support industry standard 10BaseT Ethernet
communications, the H2-EBC100 supports industry standard 10/100BaseT Ethernet
communications,and the H2-EBC-F module supports 10BaseFL (fiber optic)
Ethernet standards. All of the EBC modules are compatible with TCP/IP,
IPX and MODBUS TCP/IP (H2-EBC100 only) protocols for flexible PC communications.
The T1H-EBC100 module supports TCP/ IP, UDP/ IP, IPX and the MODBUS TCP/IP
application layer protocol at 100 Mbps maximum.
Easy to use, reliable and fast!
The H2-EBC(-F) and H2-EBC100 modules plug into the CPU slot of any DL205
I/O base and support all DL205 discrete and analog I/O modules, and the
H2-SERIO and H2-CTRIO specialty modules. All EBC modules can be configured
using NetEdit3, a free Windows software utility. The H2-EBC100 also supports
HTML configuration.
Off-the-shelf solutions
You can purchase PC-based control software that is ready to use with the
H2-EBC100 or H2-EBC(-F) module. PC-based control packages are equipped
with compatible I/O device drivers, program development tools, and run-time
environments. See the "PC-based Control Products" section of our Web site
for a single-source integrated PC-based control solution that ships with
everything you need to make your PC into an industrial controller. Most
of the software packages allow you to connect serial devices, such as
barcode readers, to the H2-EBC100 or H2-EBC(-F) serial port.
T1H-EBC as H*-ERM slave
The T1H-EBC module provides a low-cost Ethernet link between Terminator
I/O and your WinPLC/ DL205/ DL405 CPUs using the H*-ERM module for remote
I/O. When using a DirectLOGIC CPU with an ERM module as
the network master, the T1H-EBC slave will provide faster analog I/O update
times than the same CPU system with a T1K-RSSS slave system. The ERM/
EBC system can also support a much higher analog I/O count than the T1K-RSSS
remote I/O system. The T1H-EBC supports the full lineup of Terminator
I/O discrete and analog modules.
T1H-EBC100 as H*-ERM slave
When using a DirectLOGIC CPU with an ERM module as the network
master, the T1H-EBC100 slave will provide faster analog I/O update times
than a DirectLOGIC CPU system with a T1K-RSSS slave system.
The ERM/ EBC system can also support a much higher analog I/O count than
the T1K-RSSS remote I/O system.
EBC modules offer:
- Lower cost on your DirectLOGIC
PLC I/O system when compared to competitive I/O alternatives
- Virtually unlimited number of I/O points
- Deterministic I/O updates on dedicated
networks
- Fast I/O updates (less than 1 ms per
base)
- On board serial port for an operator
panel, ASCII devices (serial port not supported when used with ERM module)
