E2618 series Modbus holding registers (continued)
Register addresses are shown 0-based, Addr in hexadecimal, Reg in decimal format.
Modbus holding register numbers MHR are shown in decimal 1-based format, and may be addressed either from 00001 or 40001 base.

RW
Sensor and analog outputs status
bit[0]=0/1 - sensor present/absent, read-only!
bit[1]=0/1 - analog outputs deactivated/activated,
bit[2]= 0/1 - in case of sensor absent, turn signaling off/on analog output1,
bit[3]=0/1 - in case of sensor absent, turn on signaling with low current/high current
on analog output1; if bit[2]==0 this bit will be ignored,
bit[4]=0/1 - in case of sensor absent, turn signaling off/on analog output2
bit[5]=0/1 - in case of sensor absent, turn on signaling with low current/high current
on analog output2; if bit[4]==0 this bit will be ignored,
bit[6]=0/1 - current/voltage output detected on output1, read-only!
bit[7]=0/1 - current/voltage output detected on output2, read-only!
bit[8]=0/1 - LED deactivated/activated,
bit[9]=0/1 - buzzer deactivated/activated,
Note
bits [8] and [9] are always 0 for E2618 series

* - The new value is applied after restart.
** - Broadcast slave ID 0 can be used to assign a new ID to device with unknown ID. When addressing by ID 0 the device shall be the
only Modbus instrument in the network. The device will not respond to Master command when addressed by ID 0.
*** - This value is dynamic and not kept in EEPROM after restart
