The use of the module 70PR05B-ES HESG332204R0001 process

Referred to in DeviceNet language as an “object”. The DeviceNet protocol is divided into various objects that describe behaviors, attributes, or information. For example, class 1 is the identity object that includes information about the identity of the product, such as the vendor identification, product type, product ID, serial number, and firmware revisions. Instance Within a class there may be multiple instances. Within the Micro-Ion ATM module there are four possible I/O instances (1–4). For example, the format for polled I/O data is instance 2 in class 5. Attribute Data that can be read from the device or written to the DeviceNet network. Attributes exist for each instance within a class. For example, the serial number is attribute 6, instance 1 in class 1 (the identity object). Master data The messages sent from the network to the device to set conditions or values in the device. Device data The messages sent from the Micro-Ion ATM module to the network to communicate values, attributes, or other information.The rate at which data is transmitted (125, 250, or 500 kbaud, switch selectable).

Explicit messages

 Messages that are used for request/response communications enabling module configuration and problem diagnosis. Explicit messages provide multi-purpose, point-to-point communication paths between two modules or other devices. Polled I/O messages Messages that are used for time-critical, control-oriented data. Polled I/O messages provide a dedicated, special-purpose communication path between a producing application (host) and one or more consuming applications (modules or other devices). Address The address of a device on the DeviceNet network.The form of the data communicated from the Micro-Ion ATM module or another node on the network. The module supports BOOL, BYTE, SSTRING, REAL, INT, UINT, USINT, EPATH, and WORD data types.Install raw cable that has a braided shield over the aluminum foil-shielded signal and power wires. On the module end of the cable, install a metal housing so the shield is continuous from the cable to the gauge housing. Do not ground the shield at the receiver or output device.

Optional Digital Display 

The optional digital display for the Series 354 vacuum gauge module is a 7-segment LED that indicates vacuum pressure. The display pressure range is 0.1 x 10-10 to 9.9-1 Torr. The display is OFF when power is OFF or the Micro-Ion gauge is OFF.Before you install the module, you should install appropriate pressure relief devices in the vacuum system. Granville-Phillips does not supply pressure relief valves or rupture disks. Suppliers of pressure relief valves and rupture disks are listed in the Thomas Register under “Valves, Relief” and “Discs, Rupture.Exposing the module to moisture can cause fire or electrical shock resulting in severe property damage or personal injury. To avoid exposing the module to moisture, install the module in an indoor environment. Do not install the module in any outdoor environment.Using the module to measure the pressure of flammable or explosive gases can cause a fire or explosion resulting in severe property damage or personal injury. Do not use the module to measure the pressure of flammable or explosive gases.
