Abstract
A data error detection method for a bit, byte or word oriented network wherein a protected data unit 46 and an associated data check unit 50 are addressed to a particular field device located on the network, 10 or 26. The data check unit 50 is derived in a particular manner either solely from the protected data unit 46 or from the protected data unit 46 and particular binary codes representing attributes of the network 10 or 26 and the field device sending the protected data unit 46. The particular configuration of the checking data unit 50 is such that the receiving field device or the host 22 can perform a bit-by-bit comparison of either the received protected data unit 46 or data check unit 50 with a protected data unit 46 or data check unit 50 derived in the particular manner by the receiving host 22 or field device 14 or 18.
