Appendix 4.3 Examples of calculation for character string information
parameters
This section describes examples of calculation for the total size of character string
information parameters using the setting examples described in Appendix 4.2.
(1) Total size of character string information parameters used in Nic No. 1
(a) Nic Name
Nic Name = 14 characters ("MY_NIC_NAME_01")

According to (a) to (d), the total size of character string information parameters used
in Nic No. 1 is obtained by: Header + Nic Name + Node Name + Tag name + Data
Type name, Define name + Footer = 9+8+528+524+549+1 =1619 words.
