VMSE Firmware Options
The IC200SET001 VMSE has multiple 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 Firmware
The SRTP/SNP firmware is used to connect GE Fanuc PLCs or other devices, which
support the SNP protocol, to Ethernet.
Devices that support GE Fanuc Ethernet (VersaPro
, CIMPLICITY
HMI, Series
90-30
, Series 90-70
, and 3
rd
party devices) can communicate with GE Fanuc
PLCs with a serial SNP port by using the VMSE with the SRTP/SNP firmware. This
firmware handles the conversion from GE Fanuc Ethernet (SRTP) to SNP and also
handles the timing requirements of SNP.
Note: The VMSE can not handle multidropped SNP devices if the communications
is originating from a device using SRTP. To multidrop SNP Slaves off of a VMSE,
another VMSE is required at the Master end and the Master needs to send messages
via SNP not SRTP.
Pass Thru Firmware
Pass Thru firmware is used to connect other serial protocols to Ethernet. Typically
this firmware is used to send serial communication and use the Ethernet to replace
serial cables by using two VMSE units one at each end. Pass Thru Firmware can also
be used with a PC software package that communicates Ethernet to a VMSE unit,
which, in turn, converts the Ethernet messages to a serial message to communicate to
the end device.
Some examples of using Pass Thru firmware are:
•
Logicmaster
6 to Series Six
CCM Type 2 card
•
PC Application to a CNC
Modbus
TCP/RTU firmware
Modbus TCP/RTU firmware is used to communicate between devices that use
Modbus TCP to allow them to communicate to devices that use Modbus RTU serial
protocol.
