Page 8: Beckhoff Identification Code (Bic)
01 - hardware version 01 Beckhoff Identification Code (BIC) The Beckhoff Identification Code (BIC) is increasingly being applied to Beckhoff products to uniquely identify the product. The BIC is represented as a Data Matrix Code (DMC, code scheme ECC200), the content is based on the ANSI standard MH10.8.2-2016. - Page 9 Example of composite information from item 1 to 4 and 6. The data identifiers are marked in red for better display: An important component of the BIC is the Beckhoff Traceability Number (BTN, item no. 2). The BTN is a unique serial number consisting of eight characters that will replace all other serial number systems at Beckhoff in the long term (e.g.

Page 10: Product Overview
Product overview General The KL3361 and KL3362 oscilloscope terminals enable decentralized pre-processing of analog input data. The input values are digitized with a 14-bit resolution and written into an internal memory. A powerful pre- processing processor can determine or monitor the following values, among others: •... -

KL3361 - Single-channel oscilloscope terminal Fig. 2: KL3361 The KL3361 analog input terminal makes it possible to perform non-central preliminary processing of analog values. The input values are digitized with a 14-bit resolution and written into an internal memory. An efficient processor can pre-process the values. -
