Each input port of this device may be mapped to the same port of another WEB BROWSER Acromag 982/983EN-4012 digital I/O module (different IP address). Subsequent messages will be sent at a periodic rate specified via the update I/O Mapping Page time. - Page 17 For example, Enter a state value of “0000” to turn OFF (open) all port outputs (failsafe state) upon watchdog timeout. You would enter “000F” to turn all port outputs ON upon watchdog timeout. Acromag, Inc. Tel:248-295-0880 Fax:248-624-9234 Email:sales@acromag.com ttp://www.acromag.com...

Page 22: About Modbus Tcp/Ip
Acromag’s 901/902/903MB ModBus modules. The operation over Ethernet is essentially transparent to the Modbus register/command structure. If you are already familiar with Modbus or with Acromag Series 900MB modules, then you are already familiar with the operation of the 981/982/983EN modules. - Page 23 The subnetwork address of 128.1.1.0 has 254 possible unique node addresses (we are using node 100 of 254 possible). Nodes 0, 10, and 255 are typically reserved for servers and may yield poor results if used. Acromag, Inc. Tel:248-295-0880 Fax:248-624-9234 Email:sales@acromag.com ttp://www.acromag.com...

FF00H will turn the coil ON. Writing to multiple coils is not supported via register mirroring, you must use the “Write Multple Coils” function for that. Note that with respect to the Acromag 9xxMB Modbus RTU modules, only the 3xxxx Input Registers are mirrored into 4xxxx space, not Coil or Input Status registers as noted here for 9xxEN models. -
Page 27: Register Map
The Modbus functions operate on these registers using the data types noted above (except for the Reset Slave and Report Slave ID functions). Note that this register map is very similar to the register map of Acromag 901/902/903MB ModBus modules, except that registers for slave address, baud rate, parity, turnaround delay, and reset have been removed. - Page 28 4, bit 1 to 983EN Only) channel 5, bit 2 to channel 6, and bit 3 to channel 7.

TIA/EIA 568A standard. Category 5 cable includes four twisted wire pairs at eight twists per foot. This device is designed for use in harsh industrial environments. Acromag recommends the use of shielded cable when wiring to this device. Select STP (Shielded Twisted Pair) cable rather than UTP (Unshielded Twisted Pair). - Page 36 Note that you do not need to use a crossover cable to connect your PC to this module if the Acromag 900EN-S005 switch is used between the PC and module, as the switch is auto-crossing. However, you must use a crossover cable when directly connecting your PC to a Series 9xxEN I/O Module without the use of an auto-crossing switch or hub.
