1.526 Pico-EnviroMon-EL005

This page describes the device driver and the device window for the Pico EnviroMon EL005 temperature logger. The sat-nms device driver for the EL005 logger is capable to monitor up to the first 8 temperature sensors connected. The driver simply provides the live readings of the temperature sensors, it operates the EL005 as a simple 8-channel temperature sensor.

The driver does not provide any means to configure or setup the EL005 device. This has to be done using the EnviroMon software coming with the logger before it is connected to the sat-nms system.

The internal logging capabilities of the EL005 can be used in parallel while the EL005 is connected to the sat-nms M&C. However, to read out the stored readings from the EL005, it's RS232 interface must be disconnected from the sat-nms M&C and connected to a computer running the Pico EnviroMon software. For a more comfortable logging of the temperature readings we recommend the usage of the File-Recorder logical device in the sat-nms software.

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

• --- Shows the actual temperature values.
• --- The faults page.
• --- The device info page.
• --- The maintenance page. The configuration parameters described below are set at this page.

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which are used to configure the device driver.

• parameter --- description
• address --- Doesn't matter. The communication protocol to the temperature logger uses a fixed address (RS232 point-to-point communication), ignores any address entered here.
• sensors --- Select the number of temperature sensors (1..8) to be monitored. The number set here must be less or equal the number of sensors configured at the logger. It is possible to configure 10 sensors at the logger, but only monitor the first 5 of them with the sat-nms Software. If the driver is set to monitor sensors which are not configured at the logger, an arbitrary temperature value will be displayed for the non-existent sensors.
• name.0 ... name.7 --- You may enter a descriptive name for the location of each sensor (numbered 0..7) or the meaning of the temperature value. A name/description set here is not an equivalent of the name configured for the sensor with the EnviroMon software. The sat-nms Software is not capable to read or set the EnviroMon sensor descriptions. The names of sensors which are not enabled (beyond the number of sensors selected with the 'sensors' configuration parameter), are displayed with a gray background an cannot be set.
• scale.0 ... scale.7 --- With these parameters you can adjust the decimal places for each individual sensor (numbered 0..7). The EnviroMon logger sends the actual temperature as an integer number in hundreds, tenths or full centigrade, depending on the decimal places configured for the individual sensor in the EnviroMon software. You have to set the scaling for each sensor in order to make the value appear correctly:

The scaling values of sensors which are not enabled (beyond the number of sensors selected with the 'sensors' configuration parameter), are displayed with a gray background and cannot be set.

• Serial --- The EL005 logger operates at 57600 baud, 8 bits, no parity, no handshake.

Configuration hints

• To make the EL005 logger work with the sat-nms software, it first must be setup using the EnviroMon software coming with the device.
• All temperature sensors should be configured to record Centigrade. If a sensor is configured to record Fahrenheit, the sat-nms software will show the correct (Fahrenheit) numeric value followed by a "C" for Centigrade.
• You only can use temperature sensors with a EL005 monitored by the sat-nms software. Mixing temperature and alarm circuit sensors breaks the data structure sent to the M&C, the sat-nms software will display nonsense in this case.
