Setting the IP Address

Key items to remember when setting the IP address on the
VersaMax Micro Ethernet module (IC200UEM001):

▪ When connecting via Ethernet point- to-point, a crossover

cable is required.

▪ IP address setting must be saved to the Flash on the

Ethernet module or it will be lost during power cycle.

▪ The second port of the Micro PLC must be configured for

Ethernet.

Downloading is done using the PumpKIN utility, which is

included. To download a driver, perform the following procedure.
Only one driver can be present at one time. After the driver has
been downloaded you will have to reconfigure the port using

Security Settings
Note: This information replaces the “Security Settings for the
Ethernet Option Module” section in chapter 14 of

that manual.

the Micro PLC (for example: 10.10.0.2).
These parameters allow you to configure the Telnet password,
enable the required ports and disable the unused ports

Note: We strongly recommend configuration of the Telnet

password and closing the unused ports. This will reduce
the exposure to security threats.
These ports are disabled by default. A port must be enabled if
the application needs a service associated with that port.
For firmware upgrade, the TFTP Download must be enabled.
For connection with Device Installer, Port 77FE must be enabled.
For use as web server the configuration for Web Server must be
enabled.
By default, Simple Network Management Protocol (SNMP) is
Disabled.
For Modbus TCP and SRTP protocols, these security settings

following: (Passthrough), these security settings are in "basic
parameters/server" menu.
The maximum password length is 16 characters. These
characters can be alphanumeric or special characters. The
password requires a minimum length of 8 characters.
A password set on a protocol’s firmware remains in effect if the
firmware is changed to that of a different protocol. For example,
if a password is set on Modbus TCP firmware and later the
firmware is changed to SNP/SRTP, the same password set on
Modbus TCP firmware will still apply.

Upgrades
All previous versions can be upgraded to this firmware version.
Once the module is upgraded to the 3.3 version, it will not
support downgrade to older revision. Attempting to downgrade
firmware may cause the module to fail permanently.
Note: To reduce the risk of this being accidentally or
maliciously used, to permanently disable the module,
Emerson strongly recommends that TFTP be disabled

by the user, and only enabled via (password-protected)

telnet when a firmware update is required.

Functional Compatibility
The default data rate with Ethernet option module firmware
version 2.0 is 175000 bps. Micro firmware versions below 3.83
do not support 175000 bps. If firmware version 2.0 is to be used
with Micro firmware versions prior to 3.83, the data rate on
Ethernet Option module should be changed to 38400 bps or
less, as per the requirement.

Problems Resolved by this Revision

The Firmware release 3.3.0.7 (IC200UEM001-CF) fixes issue of
inconsistent Modbus communication for different baud rate
settings. This firmware upgrade can be done on CD and earlier
versions of modules.

Note: The Ethernet option module will be power cycled and reset
under the following conditions:
A connection to the Ethernet option module is established
through TELNET and disconnected immediately.
