Notes
Ethernet remote I/O with a built-in Modbus/TCP server; no gateway needed. Addresses are the manual's decimal start addresses, which are the zero-based wire addresses (the manual also prints the 1-based reference numbers). Each channel occupies one address in the start-address table, so this map lists channels separately. Source: Moxa ioLogik E1200 Series User Manual v16.2, appendix A, 'ioLogik E1240 Modbus Address and Register Map' (8 analog inputs). Raw values are 16-bit ADC counts covering the selected input mode, and the scaled values are 32-bit values carrying the point-slope engineering unit, so no scale factor is applied to either. The manual's AI channel object table (REST/SNMP) types aiValueScaled and aiBurnoutValue as REAL, which is why those rows are Float32. Unit identifier: the manual states that the Modbus/TCP ID of the ioLogik E1200 is set to 1 by default, so unit_id 1 is used.
