MELSEC Device Codes
For user convenience, the gateway provides internal support for a certain number
of device codes (refer to Table 7). However, this in no way limits the variety of
device codes that the gateway can target. The user has the ability to specify any
device code that is supported by the targeted MELSEC server equipment (refer
to sections 8.7.9.2 and 11.7.3.3.5). Note that device codes are not case-
sensitive (i.e. “C3” is interpreted the same as “c3”).
