Introduction
Introduction and Quick Start
The VersaMax IC200SET001 Serial to Ethernet Adapter (VMSE) brings network
connectivity to factory floors. It is designed to connect industrial devices with serial
interfaces to an Ethernet network using the TCP protocol family (TCP for
transparent s tream- and UDP for datagram ap pl ications). Var ious devices can be
interfaced, for example:
•
PLCs
•
CNC Controllers
•
Terminals
•
Time/attendance and data collection devices
•
Industrial robots
•
Data display units
•
Instruments

VMSE Firmware Options
The IC 2 00 SET001 VMSE h as multip le firmware choices. All of the choices are
shipped on the CD that is shipped with the VMSE unit. Upgrades and new firmware
choices will be placed on the GE Fanuc WEB site, as they become available.
The VMSE ships with the default SRTP/SNP firmware loaded in flash memory.
SRTP/SNP Firmw ar e
The SRTP /SNP firmware is us ed to connect G E Fanuc PLCs or ot her devices, whi ch
support the SNP protocol, to Ethernet.
Devices that support GE Fanuc Ethernet (VersaPro, CIMPLICITY HMI, Se ries
90-30, Series 90-70, and 3
PLCs with a serial SNP port by usin g th e VMSE with the SRTP/SNP firm ware. This
firm ware handles the con version from GE Fanu c Ethernet ( S RT P ) to SNP and also
hand les the timing requ irement s of SNP .
Note: The VMSE can not handle multidropped SNP devices if the communications
is or igin ating from a device usin g SRTP. To multidr op SNP S l aves o ff of a V M S E,
another VMSE is required at th e Mast er end an d the Mast er needs to send messa g es
via SNP not SRTP.

Pass Thru Firmware
Pass Thr u firmware is used to connect other serial protoc ols to Ethernet. Typically
this firmware is used to send serial communication and use the Ethernet to replace
seri al cables b y usi n g two VMSE units one at ea ch en d. Pass Th r u Firmwar e can also
be used with a PC softwa re package that com municates Ether net to a VMSE un it,
which, in turn, converts the Ethernet messages to a serial message to communicate to
the end d evi ce.
Some examples of using Pa s s Thr u fir mware ar e:
•
Logicmaster 6 to Series Six CCM Type 2 card
•
PC Application to a CNC
Modbus TCP/RTU firmware
Modbus T C P /RTU firmwa re is used to communi cate between d evi ces that use
Modbus TCP to allow them to communicate to devices that use Modbus RTU serial
protocol.

Introduction and Quick Start
The easiest way to configure the IC200SET001 VMSE is over Ethernet. The
follo wing step s need to be don e, in the ord er listed, to config ure the VMSE.
Preliminary S tep

The VMSE is shipped with a default IP address of 0.0.0.0, which automatically
enables the DHCP wi thin the VMSE.

Procedure: Assigning a New IP Address
Use th e fol lowing s teps to assign an IP address over the network. All of the
follo wing are done from the MS-DOS prompt of your personal c omputer. The
actual numbers and letters you must type are shown in bold type. This data is not
case-sensitive. You can access the MS -DOS prom pt from your comp uter ’s

VMSE Interfaces
Serial Interface
The VMSE has RJ45 and screw block serial ports. The RJ45 port only supports
RS232, whereas the screw block port supports RS232 and RS485/422. By setting the
switch located on the face of the VMSE and configuring the VMSE setup, RS232 or
RS485/422 can be selected.
NOTE: The V MSE is a s in gle seria l port devi ce, meaning that only one port can be
used at a time. In the configuration menu, Chan nel One r efers to eith er one of the
ports being used.
Figure 2-1. VMSE Ports and Features
GFK-1852 2-1

Network Interface
The VMSE supports 10 Mbit Ethernet through its RJ45 (10BaseT) connector.
Hardware Addres s (MAC Addr e ss)
The first three bytes are fixed, and read 00-20-4A. The fourth, fifth, and sixth bytes
are un iq u e for each VM SE an d are used to generat e th e s er ial number . The addr es s is
in Hex notation.
Power Requirements
The VMSE is not shipped with a power supply. The required input voltage can vary
between 9VDC an d 3 0 V DC with a maximum of 3 Wat ts. The VMSE can be
powered from the 24 Volt supply on the VersaMax, Series 90-30, or an external
supply can be used. Take care not to exceed the ca pa city of th e V er s aMax or Series
90-30 power supply .

Network Protocols
The VMSE produ c t use s T CP/IP protocol s for network commun icat ion . The
supported standards are: ARP, UDP, TCP, ICMP, Telnet, TFTP, DHCP, and SNMP.
For transparent conn ection s, TC P /I P ( binary str eam) or Telnet protocols are used.
Fir mwar e upgrades c a n be made wi th th e TFTP protocol.
The IP protocol defi nes addressi ng, routing and data block ha ndlin g over the
network. Th e T CP (tra nsmission contr ol pr otocol) ass ures t hat no dat a is lost or
dupl icated, and that everything sen t into the connecti on on one side arrives at the
target exactly as it was sent.
For typical datagram applications where devices interact with others without
maintainin g a p oint to poin t con necti on , a UDP datagram is us ed .
Packing Algorithm (PassThru Firmware only)
The two ava ilabl e pa ck et algorithms (wh ich define how and when pa ck ets are sent to
the network) are software select able. The standard algor ithm is optimized for
applications where VMSE is used in a local environment, allowing for very small
delays for sing le chara cters while trying to k eep the packet count low. The alternate
packing algorithm minimizes th e packet count on th e net wor k , and is es p ecially
useful for applications in routed Wide Area Networks. Various parameters can be set
in this mode to economize the serial data stream.
IP Address
Every active device connected t o the TCP/IP n etwork must h ave a unique IP address.
This IP address i s us ed to reference a specifi c d evi ce, for example, to build a
connection to the VMSE’s serial port. See Appendix A for a complete description of
IP Addressing.
GFK-1852 3-1
3
Port Number
Every TCP connect ion and every UDP dat agram are d efined by a destinati on I P
addr ess and a port number. An IP address is n ecess ary to ad d r es s a device (h ost) on
the net wor k. A port nu mber is neces sary to ad dress an ap p lication or a ch an nel on a
networ k host. Th e port n umber can be comp ared to an ex tension on a PBX
(telep hone) system.
A Telnet application (login to a host with an ASCII terminal) is commonly assigned
TCP por t n um ber 23. Mor e th an one Teln et connection can be establi s hed to one host
using the Telnet port; however, the other peer IP address/port number combination
must be di ff eren t.
In th e VMSE (PassThru Firmwar e) , a port number can be confi g u red on th e ch an nel
(port). The VMSE uses this port number for outgoing messages and incoming
connections or UDP datagrams, which are addressed to its port number. Port 9999
(decimal) is used for remote configuration.
