6.10 EWON IO Server
6.10.1 Introduction
The eWON IO server is used to interface the eWON INPUTS and OUTPUTS.
Depending on your eWON model, you have:
• Digital inputs
1 on eWON500/2001/4001
9 on eWON4002
• Digital outputs
1 on eWON500/2001/4001
3 on eWON4002
• Analog inputs
None on eWON500/2001/4001
6 on eWON4002
Additionally, there are a number of Tags that can be addressed with this IO server and which are computed by the eWON IO Server.
These additional Tags are used for energy management. In Energy management, the following requirements are taken into accounts:
• Using digital inputs as counter inputs
• Count for a given interval and latch computed result (also save it in historical)
• Reject the measurement interval if too long or too short
• Adjust eWON’s Real Time Clock based on a digital input
These Tags will be computed if the energy module is enabled.
There is no topic name to define for the eWON IO server.
6.10.2 Standard eWON I/O Item Names
6.10.2.1 Tag name convention
The following Tags are available for standard eWON Inputs & Outputs access:
NOTE:
The button input (BI1) can be used during normal eWON operation, if it is pressed for more that 4 seconds while eWON is booting;
the flash file system will be erased (please refer to chapter “The eWON firmware upgrade process” on page 229).
(1) The number of item depends of eWON type. See table Table 79 on page 107.
(2) From firmware 4.1S3 to 4.3, the CIx value wrapped at 1.000.000.
Before 4.1S3, the CIx was misinterpreted as negative when value passes over 2
