Handling the Module
ATTENTION:
This RS-232 module uses CMOS technology
, which is highly
sensitive to electrostatic dischar
ge (ESD). ESD may be present whenever you
are handling the module.
T
ake these precautions to guard against electrostatic damage:
•Avoid touching the interface connector pins on the RS-232 module.
•If the module is not in use, store it in the anti-static bag in which it was
shipped.
It is not necessary to wear an ESD wrist strap while handling the 1770-KFD
module.
Terminology
this term means
DeviceNet an open communication network designed to connect control
systems to plant floor devices, e.g., sensors, push buttons,
motor starters, and drives
DeviceNet is based on commercially available technology and
can be used by any company to develop interoperable
products.
node configuration to configure the node address and data rate before a device is
connected to a DeviceNet network
parameter configuration to configure the operational parameters of a DeviceNet device
